I had my S2 on rolling road to day.. BUT i showes that I is running lean after 4100 RPM.. in fact after 4100 rpm it running like shite

the spec is:

1600cc std wit
turbosystem 195 chip
piper 285t2
mongoose
K&N
-34
GRS

its running bout 1,2bar i boost.. and I've turned it up to 3.5% i CO.. is this enougf??


can the std MFI deal wit this spec and boost... or is something wrong.. cause it was just when the engine really needed the fuel and the boost was high, that it under fueled it??

I going to fit MF2 very soon

by the way.. the car had 163bhp.. and it had i at 4100rpm... and i still had it a 6300rpm... so something is obviosly wrong

 

mfi can cope with that no worries, im sure it can cope with upto 210/220 np.

 

did they adjust the pressure actuator at all and was the tps checked?

 

the didn't adjust anything... I have adjusted my actuator me self... tps???

 

Throttle position sensor, check it clicks when the cable starts to open the throttle, im not sure if you can test it another way

 

not the actuator, the fuel pressure actuactor on the side of the metering unit that enichens the mixture.
Also has it got a dump valve if so what make is it?

 

hmm.. I think I will go out and tjeck that tps.. but what does it do exactly??

the pressure actuator havent been touched... some say its not nessery and some say it is.. dont know what to belive..

I have e bailey d/v on it.. but i've been tolded taht you need to run a twin pistion d/v on a RST or els it would run lean??????

 

I've put my own custom inlet on my s2 with 2.5 inch charge pipe and new grs, it's running real lean, it's a 90spec. on my meter unit there is a black box and a grey box on the side, which 1 has the 3mm hex key inside, I was going to jam an emission tester up the exhaust and give it a quarter turn, see if it helps any advice appreciated.

If you change any of the settings on the engine chances are it will run worse than it was in the first place. Take it to a tuner and let them sort it properly or read the setup guide i have written to help you tune it best you can without a tuner.

 

were is the set up guide? do you have a link to it?

 

i think he can't give the link.... Think stronger and you will find the answer....!!
