Re: E85 back to Pump 93

You have a chipped ECU right? JWT? Chances are you have a bad capacitor or something like that in your stock ECU. I figure this out on mine yrs ago and sent the JWT ECU and a good used one to Jim Wolf and just paid him to move his hardware over to the replacement. I experienced the exact same proble...

Re: E85 back to Pump 93

Sounds like the ECU. Capacitors failure if I had to guess. If you have a JWT ECU then you can send him a replacement computer along with yours and pay them to move their board over to the replacement ECU. This is what I had to do. The wide band and narrow band signal are reading correctly and accura...

Re: E85 back to Pump 93

Correct. I experienced a similar issue years ago when i was still running tuned stock ECU. I'm assuming you are getting your O2 voltage values from what the ECU sees. If this is true I would disconnect the narrow band signal and check with the signal voltage from the O2 with it disconnected. There i...

Re: E85 back to Pump 93

Are you running stock O2 sensor still for the computer? If so, what's your O2 voltage reading from cold to warm? OK... so upon COLD start the O2 sensor (narrowband output from wideband) reads .44V upon cold start with wideband reading 14.7, then stays solid for about 30 seconds when the O2 voltage ...

Re: E85 back to Pump 93

So what's your MAF voltage reading after starting the car and it begins to go rich? Record your readings. Then check the O2 sensor voltage reading as it richens up? You already checked coolant so we can weed that one out based on your info you gave us.

Re: E85 back to Pump 93

That's great that the sensor is working correctly but how do you know that signal has made it all the way back to the ECU? You can perform an ohm test on the two wires from the ECU. Also want to do the same for the O2 sensor signal which can alter AFR's. If all this checks out then its my opinion th...

Re: E85 back to Pump 93

Check to see what water temps your ECU see's during these different water temps. Especially when 160 degrees and under. This is to confirm water temps sensor is still within range and report back.

Great Job Adam. Yea, KA's are remarkably reliable when built properly and not being cheap on the setup. As you turn up the power you will really love the car. 22 psi is my daily and I love it at that level for daily driving.

How are you tuning your car Adam when it comes to ignition timing? What compression are you pistons and what thickness head gasket are you running?

Re: S14 KA-T Boost issues

You need a TEchtom or DataScan to see all your values. Specific values I can think to be looking for is MAF sensor, coolant, CAS sensor signals , Injector pulse width before and after the engine starts to give the problem. I would start there.

Its set to 8200. I just usually shift earlier when clowning around. Only when I'm serious I will run it all the way out. No need it pushing it that far for no reason. At least that's how I see it on a street car.

Thanks guys. Yea I do all my own tuning. I honestly left more power on the table. Never even had a chance to add more timing or make any more adjustments due to the intake. One of these days I may play with it again on the dyno but I okay with these numbers.

Not a bad day at the dyno today. I stopped at 843 when I blew the weld on my intake manifold.

Still more left in the motor but I'm gonna leave it right ...

These washer inserts are for anyone using high torque studs (L19,625 materials). As far as stud diameter it doesn't matter.
