Ignition timing has nothing to do with it.BMCC wrote:What about the ignition timingf? You were getting high a/f ratios before but now it looks like your running rich? Do you not need to adjust the ignition timing when running the charger? Is the ECU set up to do this?
Have you been cranking the engine alot without getting the car to start?
Where about is the lamda sensor in your exhaust?
You should be able to install the supercharger on any H22 and use it fine without a tune. But once you give it boost it will need to retarded and advance etc. I need the car to runa dn drive fine off boost so i can drive it to the tuner. I can even tie the bypass valve open constatly so i never sees boost.
The charger has a bypass alve that it uses on overrun and at idle so it behaves identical to a N/A car.
All i have done is use my greddy E-manage ultimate (GEMU), used the h22a base map and changed the lag times and sizes on the injectors. The car ran fine N/A with the GEMU and was running super rich before i changed the injector lag times.
I changed the lag times and it was at 14.7ish but the bypass valve wasnt being used as i wired it up wrong. It was using the charger but was still at -20 vacuum.
The primary O2 sensor is brand new OEM. before the decat. The innovate MTX-D o2 sensors is next to it but on the decat pipe at exatly the same angle.
So if my plugs are black why are my a/f at 20:1, why was my vacuum at -17 and then rises to -15 at idle.
Unless there is a PCV issues. OR there is a vacuum leak somewhere causes the super lean conditions.
I was thinking of getting a boost tester so i can find leaks without the engine on and use soapy water since the carb cleaner is stripping the paint off all components.
