Non-Stop 3b upgrade

[vertigone]

Hello Rocco

Got them too but gave me some strange surging

Will you regap them because gap is diffrent from f5dpor one ?

Waiting your feedback :thumbup:

[Rocco]

new Spark plugs

There is better then vems if you have more money.But that what spending on Motronic tune and all things around that is cheeper and better vems.

Vems FTW:-P

Motronic FTW

[Rocco]

I have vems and I would say is cheaper then Motronic tune.I can do a lot ajustments my self.My friend done good job programming it to max,and now if I need any correction I can do my self.I will connect methanol injection this winter so can go for more power and will be more safe.There is a lot info how to program ecu like vems or other.On Motronic you must ask some one like PRJ every time then you changed some part or you wont more boost.

ok mate,thanks to share your experience

[Biturbo]

got EGT,AFR,Boost, sensors and a SLC Pure Plus 2 data logger

problem is that Motronic is cheap and works very fine,,,and while Prj wants to come,...

the thing is i dont know how to tune on Motronic or any other ECU...and starting playing with a 4 Zeros engine is not the best option.

hopefully Dmitri will come soon,if not he is a gay



do you know how to tune yourself your race engine?

on wich ECU?

Why you not going for programming ecu?Would be easy in your position.You can have 2 maps, lc, shift light, egt sensor connected, logs.And can always adjust fuel if is too rich or to lean.

thanks Vas, i have read that almost all meth in the mixture could convert your AFR 1 point richer


definitely i need to re-tune the car.


2 maps, one for water/meth and the other for only 98 octane fuel

when you turn off manually the aquamist if you dont have the spare map for fuel it just convert your boost mechanical... 0.9Bar in my case... and it does the same if your water/meth level is low.


Vas,how many degress of IAT can low your water injection system over running without it with just the fuel mapping?

25% of meth wont make the after that much richer. Nothing that you could notice at least. I use something similar and didn't have to change the map at all. Went from 0.80 to 0.79/78 lands occasionally.

some test were done¡¡

new ECU with the race enginee chips and the iddling problems and turning off problems has dissapeared¡¡


well, i think the engine needs a bit of fine tuning...because is a little too rich in all conditions.

just example:

iddling at 950RPM AFR is 12.85 (more or less)
full boost conditions at 2.2 bar , the richer AFR is 10.35 /5...

car stopped and 2K rpms AFR is around 12.5

i have to say that in boost conditions the engine uses Aquamist HFS3 at 25% meth and 75% water. so i will try to add more water to complete a mixture of 10% meth and 90% water...then the AFR must be more leaner because the meth makes richer the mixture if you dont have custom mapping for it. AFAIK of couse.


next step is try the car without DV...to see the behavior when shifting from 3 gear redline to 4TH... because the electronic boost dissapear (2.2bar) and it only makes mechanical boost (0.9Bar because my wastegate spring) .... and in the first moment you release the thorttle and WOT again,then 2.2Bar again¡¡

[Rocco]

Ecu received today.

I have to check if it works like it must and it doesn't stops the car with a little hit.

I'll do test later but today is the tarmac wet....


Afr at iddle is 13.5 ,with of course engine hot.

OK,then my wastegate must be old and tired...and the gas pushes it through the valve.

No, this is a wrong conclusion. The opposite is true. The wastegate tolerance is too tight so it jams if it is the wastegate.

Try to block the dump valve and see if it is better.
Check fault codes, maybe there is an overboost condition, etc.

Remember you took a highly tuned engine from one car to the other, the intake has been changed, there are problems with how it runs (too rich) and so on.

This is also why copy pasting chips is a really bad idea.
