My spec is 1 bar boost on JAM ECU on a speedvision hybrid and have all supporting mods.
Was racing a Porsche last week and got ahead of myself, revved too high and spun a bearing, had a 4EFTE engine in my shed and got that in (was running perfect when taken out of the previous car around 10 months before hand)
Got the engine in that day and also reset the ecu. I got a new lambda from a 1.5 civic (single wire one presumed they're all universal?) and the only problem I had was knock sensor had dirt in the thread and this caused it to not get a reading throwing the EML light. I changed the knock sensor and reset the ecu.
Drove the car with the ECU in learning mode for 100 miles and took it for a blast last night.
I first noticed the boost went to .75 bar instead of .6 bar using the same wastegate pressure as before. I'm also getting boost a lot sooner 700 RPM sooner then normal (this may be because this engine has higher compression then old engine)
This was fine and I then noticed the car felt very sluggish and felt like it was being held back even at .75 bar boost. I also noticed the car popped and banged a lot more then before even would throw a random flame every now and again.
The car would barely take .7 bar boost so I drove it easy.
I disconnected the lambda sensor and took it for a blast tonight at .9 bar and it pulled well, not great but pulled better then lastnight.
It drove like this for a few hours and then one last blast the same thing started happening and the car started to over boost (shot up to 1.2 bar)
Any idea what could be wrong?
My own taught are the lambda from the civic could be calibrated differently then a starlet one?
Or else the knock sensor still has dirt in the threads causing it to pull the timing putting the car in to a safe mode?
Any suggestions welcome.
