YRV Turbo ECU remap/ Unichip-q/E-manage

Forum: 

Hello All,

I have currently amased some modifications to my YRV turbo, and now looking to have the ECU mapped to take advantage of these upgrades. I am under the impression the standard ECU on the YRV cannot be mapped or can it?
Also doing some research and asking others here on the forums it appears that there are other options available:

- Unchip -Q piggy back system

- E-Manage blue piggy back system.

At the moment the car feels quick, but have the following when pushing it:

- Fuel cut (brick wall effect) due to turbo overboost being caused by the straight through Blitz Nur-Spec R exhaust system

- 2nd gear feels sluggish

- More torque would be nice Smile

Anyone any ideas?

Jon.

Unichip Q

Well I have had 2 cars with Unichip, the first one was the previous version on a 1.6 Toyota, the second on a 2litre nissan with open throttles. Both were fuel injected and had plenty modifications. The only drawback I found was mainly with the previous version of the unichip, which was seasonal changes and gradual dropping out of tune over months. But most of those were ironed out with the Q version.
The biggest limitation was getting a good tuner. The piggy back chip maps are only as good as the tuner setting them up. In the end I had it done 4 times before I was happy, and the differences between each of those tuners was quite a lot (35hp between the best and the worst).
After a year of reliable running, I changed to full aftermarket management as that was tuned on the road with a laptop and not on a dyno/rolling road where airflow and resistance is not always the same as reality, so I gained another 20hp!
Dont have experience with GReddy E-manage, but if it can fulfil the same duties, it seems a bit cheaper in price, havent looked at it in detail.
Whats important to consider are the increments in the fuelling and ignition maps, the inputs it reads from and compatibility with the TPS and MAF sensor and probably the ability to withstand huge temperature variations between -10 and snow to high 20's in summer with a variety of humidities.
I personally wouldnt tamper with the ECU, its always nice to have a fall-back if the piggyback doesnt operate as it should, cos u can just bridge it out and ride on normal ECU parameters.
You will be guaranteed to get loads more torque with any turbo car being chipped.
Believe it or not, I am getting the brick wall at about 5000rpm from only a cone filter and no middle silencer box with a slightly bigger pipe in just that section!!
So I am also looking ahead to possibly getting chipped...

Thanks for replying

Hi G!

Thanks for your comments. I am finding it increasingly hard to find a mapper for the YRV Turbo. I contacted a tuners after investigation on here called 'bigperformance.co.uk' based in Surrey . When I mentioned the YRV I was told they can map the standard car from 85BHP to 100BHP but hadn't tuned the YRV Turbo before, but thought he could get 150BHP.

Another tuner who is well known on scoobynet.co.uk called jolly green monster, said he had tuned a car on the e-manage system but it was a toyota starlet turbo. I beleive a couple of memebrs on here based in South Africa have tuned their cars using the unichip-Q system.

Decisions...decisions.

Unichip Uni-Q

Why don't you talk to Unichip Europe, based near Abingdon at Kingston Bagpuize? They will be able to fit the Uni-Q for you and set it up.

They are the new importer for the Uni-Q and are part of Owen Developments, which has a four wheel drive rolling road (with a massive (56,000CFM) cooling fan and loads of experience with building and mapping turbo cars on a variety of engine management systems on everything from Unichip to MoTec.

Log onto www.unichipeurope.co.uk and give them a call. You need to speak to Henk Gouws, who is the South African MD in charge of the program.

Unichip Uni-Q

Daihatsu locally in RSA built the materia turbo, they limited it to 40 units.
I fortunatley have one.

Spoke to the technical manager who built the car
The turbo setup on the Materia was taken directly from the YRV turbo, same turbo and intercooler.
They used UNI Q to setup the car.

Compression has not been changed from the stock car, it runs .4 bar boost....May be able to push it up to .6 or .8 bar before it starts giving problem with the stock internals.
All in all 150BHP/110KW and 190NM.

Goes quite nicely and still returns good consumption figures

Thanks for the info. Maybe

Thanks for the info. Maybe now taking a different route instead of the Unichip. And it maybe cheaper too, and sort out the dreaded fuel cut.

Have found a place that can tune the YRV Turbo

Well miracles may have happened. It's taken nearly 3 years but I have now found someone who can fit the unichip-Q to the YRV Turbo and map it. And funnilly enough local to me.

Will get back as soon as I find out how much it's gonna cost. Hopefully more torque and horsepower from my mods now Smile

I can make you up a

I could make you up a electronic fuel cut eliminator (connects onto map sensor), and supply a underbonnet adjustable manual boost controller (ball and spring type which reduces turbo lag), for £50.

You could then raise boost pressure about 2-3 psi over the standard "brick wall" using this method. But no more really as it it can start to lean out on the fuelling.

I dont have any experience of the YRV turbo, but the above normally works fine for a turbo.

Thanks for the offer. Now

Thanks for the offer. Now have the Unichip-Q+ installed which already has this feature built into it. Been advised not to put the boost preasure up just yet until I can get a bigger intercooler. During the rolling road the tuner couldn't get the car upto speed due to the mini intercooler we have overheating and giving too much charge temps. Maybe tempting for those who don't want to take the Tuning route.
Oh something else said to me by the tuner, is that anything post 2000 runs a very rich fuel mixture, therefore he has mapped mine with a better fuel to air ratio. Something to consider before turnin up the boost preasure. Maybe fine in the winter and then pull back in the summer?

I really cant see the point

I really cant see the point of doing any re-mapping to increase power without also raising the boost. With a turbo, Any slight power gain you get by leaning out a rich fuel mixture brings with it a greater risk of detonation and engine damage.

Daihatsu would have set the ECU mapping to be optimum for power/economy and reliability for the boost pressure it normally runs.

There is no point touching the mapping unless you want to use more boost.

I would be very careful, It is supposed to run rich to keep the combustion temps down.

Rising inlet air temps on the rolling road is due to the intercooler not getting the proper airflow like it would on the road.

Thanks for the pointers. I

Thanks for the pointers. I beleive he managed to get another 17Bhp out of the engine and mods I have on the car. I currently run my YRV Turbo on Shell V-Power rated @ 99 RON with a blitz stainless airfilter and Blitz Nur-Spec-R Exhaust system. Also the Autobox is a lot slicker at changing gear with the car now pulling better in 3rd. Still fancy a front mount for mycar. Any ideas? Thought about one from a Toyota Glanza, with a slight mod it should fit Smile

The alloy universal

The alloy universal intercoolers commonly seen Ebay are normally pretty good quality I have found, loads of sizes to choose from and cheap. Just a case of finding one that suits the space you have.

But...with the YRV having a purpose designed bonnet scope to force direct air to the intercooler, this will actually be a hard to beat setup, the ram-air effect of that scope directing the air perfectly onto the surface of the core (once you are on the move) is not to be underestimated. Yes you can get heat soak when sitting in traffic but that will go very quickly once on the move again.

When you fit a front mounted intercooler, the airflow over the core may actually not be as good due to bumper design shape and the numberplate.

Always rememeber , The Daihatsu engineers (or infact any other car manufacturers) don't just design things a certain way for no reason. With the space available underbonnet, they would have gone for the best intercooler position and design. They want to achieve the best power figures they can.

One other thing, Big cone air filters are great for turbos, And stainless mesh air filters flow large amounts of air (hence the noise), But because of this they are poor at filtering air, you can be causing erosion damage to your turbo compressor wheel and increasing engine wear (piston rings and bores) due to the amount of dust particles that can still get through.
If your oil gets dark and dirty quicker then normal it can be a sign of dodgy air filtration.
These filters were originally used in Japan for the race track only where the only concern is to stop larger debris getting in.
I would use a oiled cotton style filter such as K&N, Jetex or Green, or for optimum filtering quality and flow, the genuine Honda huge paper/fabric cone as used on the Honda S2000, (only £32 at a Honda dealer) But it may not fit the YRV as they are huge.

Thanks Wise one Seen some

Thanks Wise one Wink Seen some filter Blitz and Apexi ones for my car, so will investigate further. And yes the oil does look a little dirtier after a couple of months just doing the normal commute.
Had toyed with the idea of a Water Spray for intercooler, but I believe the autobox plug/sensor is directly underneath it. I know it makes a difference to the temps with my Scooby as it comes with it as standard.

Ah, water spray onto

Ah, water spray onto intercooler core does do something, but it's not that effective.

However the real deal is a water injection kit, to spray a fine mist into the engine (nozzle is fitted in the boost pipe after intercooler)
WRC cars (and the old Forumla 1 cars) were banned from using it because it is so effective (which is why WRC cars only use a external spray)

Water injection (often methanol is added also) instantly and dramatically lowers the inlet air temp so well, some people have even removed the intercooler to get better turbo boost response.

Water injection will stop the engine from detonating on high boost like using a high octane race fuel, With some methonal added to the water, I have heard that it simulates 115 octane race fuel!)

Plus it steam cleans the combustion chamber/valves/pistons of carbon buildup.

Does not do any harm to the engine whatsoever, such a small amount is being sprayed in.

You can run much more boost safely (easily 5psi extra without any extra fuelling) , and also a leaner fuel mixture as the water injection takes care of temps (you dont need the extra fuel anymore to keep things cool)

Saab used water injection in the 1970's as a factory fitted option on the Saab 99 Turbo, they didn't have a intercooler as standard, power was about 130 bhp, but with the water injection kit fitted, power then jumped to 160bhp!

Aquamist are the most known company in the UK, but there prices are OTT. The AEM kits are the ones i would use. (infact i will be using it on the GTti). It's very simply to fit, and water is pretty cheap!

http://www.aemelectronics.com/water-methanol-injection-kits-23/water-methanol-systems-for-gasoline-engines-51/

Probably works out cheaper than doing a front intercooler installation (by the time you buy all the silicone hoses etc), and way more effective. On ebay the AEM kits are about £250-300.

Plenty more info on the internet regarding water injection. It's been around for years, but has only recently started coming back into fashion. Or rather, commercially available kits are now available rather than home-made setups.

I cannot stress enough how good water injection is for any turbo applications!

With these relatively cheap (but effective parts):

Boost gauge,

Big cone air filter (always choose the biggest airfilter that fits the space)

Decent exhaust (with mandrel bends) 2" - 2.5" pipe bore (preferable but not essential) and with free flow silencers. Even just decent flowing sileners fitted into the standard YRV pipework will work good.

Fuel cut defender,

Manual/electronic Boost controller.

Water injection kit.

At a guess a YRV running 15-17psi boost should be good for about 160-170bhp, no sweat at all.
No aftermarket/piggyback ECU/mapping needed. The water injection takes care of any slight leaness in the fuelling and prevents detonation.

Infact the only concern I would have is finding the torque limits of the auto gearbox.

I can make you up a

I can make you up a electronic fuel cut eliminator (connects onto map sensor), and supply a underbonnet adjustable manual boost controller (ball and spring type which reduces turbo lag hence more torque), for £50.

You could then raise boost pressure about 2-3 psi over the standard "brick wall" using this method without any issues.

How many maps?

I think the Uni-Q can handle more than one map, so are you getting the toggle switch with 3 - eg. a race map, efficiency map and a zero fuel map for immobilising the car against being stolen...
Thats a reasonable price for good technology, I think the YRV will respond very well.
Good luck!

good experience

I've had 3 cars with Dastek Unichips before. 2 of the old type and 1 with uni-Q, and all of them yielded very good results. The torque curve is always better, and peak power was always up by at least 5%. But the best is having different maps for different octane fuels. Oh and always better fuel efficiency...

Daihatsu-Tuner Can tune our cars..

All,

I have been in contact with Daihatsu-Tuner and he has come back to say that he and his company can tune our cars via a piggy back system. Also If 5 or more people were interested then it can be done cheaper. The tuning is not just confined to the YRV turbo but also the standard YRV and Sirion. Reply back to this post if you are interested. And as agreed with Daihatsu-Tuner I will post some more details. This could be an ideal opportunity for other owners to meet etc.. Smile

Interested = me

Sounds good. Would like to know more...
Why would it be cheaper if there are more people? Is it going to be a generic tune? I would've thought the same amount of work would go into each individual tuning anyway...
Is the tuning done on a dyno/rolling road?
Also the specification level of the piggyback chip, does it have only 1 map, or a switchable set of maps like the Uni-Q where 1 can be for performance (using higher octane fuel) and the other for fuel efficiency on standard unleaded fuel etc...
Are you able to bridge it out in case of a unit failure so that you can still drive the car?
And then of course, the cost and location... Smile

Location of Mappers

All,

The location for the mapping is at:

Basingstoke, Hants

As for the price. I can only gather it is cheaper as the piggy back systems can be bought in bulk. Which would make it cheaper if to say only 1 person at a time would get a map done Smile

Unfortunately this thread died a while back and I didn't want to waste the guys time as no-one else showed interest. Basingstoke is a fair bit a way from where I am. In terms of mods for the YRV. Which YRV do you have?

YRV turbo ecu map

Hi,

I've seen a webpage with an ecu map for the YRV from a company in Germany, I'll see if I can find the details in my favourites and post it.

p.s. I'm not in Germany, just where the stupid proxy is!!

happy figures

Well I would be happy with performance figures like that... I am not sure if that is what they are able to produce with a standard car or must there be some level of breathing mods...

Power 118 kW/ 160 PS

Torque 210 Nm

Top Speed 195 km/h
