Non-Stop 3b upgrade

[Rocco]

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¡¡

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.

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?

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.

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?

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

[quattrostyle]

Motronic FTW

[A80Avant]

Vems FTW:-P

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.

new Spark plugs

[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:

I installed them today morning and I did some tests!

Well,all I can say is that they works the same as the Bosch OEM,I didn't notice difference.

The car is faults free!

But I had a big problem with my wastegate controlling the boost

This coilover is the wastegate spring I found today inside!

As you can see in the pic,the big spacer in the top WAS FOUND inside the spring and down!!

The wastegate looks refurbished because it hasn't valve play ,so perfect!

So that explains my boost control problems ,shifting gears with full boost .. Also now is much more responsive to the throttle than before!!
Boost gauge shows 2.5 bar in 4/5 gears WOT ,but the motronic only reads 2.2, the boost it was mapped.

Those boost gauges seems to be not very accurates with high boost applications.

The gauge is new from the forum group buy made to rusty
