In the log I posted last, I was using 1.15 mostly, however you can see in that log, that I was getting knock and having quite a few issues. I richened it up by the advice of Tuned by Karger. Unfortunately the problem is persistent regardless. This is when I decided to post on here. I'm just extremely frustrated since no matter what I do, it bogs down or detonates.

I apologize, I haven't had the chance to check my fuel trims. I usually don't tune with them as a reference until all the major components are completed.

As you can see, there's definitely some problem areas on the MAP side of things at high Kpa.

Hopefully this allows you to get a lot more data.

This is with the same PE as the tune that I posted on here.

PM me.. The way your tune is setup you could be seeing false knock. especially with how much timing you're currently throwing at it.. your long terms are screwing you also.


you are not in SD also.

Your VE doesn't look dialed in... upper kPa range was showing a lot of red in the log file. You're around 14.7 everywhere though.

How am I supposed to be dialed in, in the upper kPa if I can't go up over 4k when tuning in SD. Keep in mind, the VE AFR error was referencing the 14.7 that my wide band was stuck at since it only has power but no signal since it wasn't plugged in.

As I mentioned before as well as in the name of the LOG file, I'm not using the wideband. It's not plugged in currently. It just had power to it.

I'll post one in SD with the wideband on it

I don't know, but you're above 80 kPa in the log file you posted in the VE table. Which means you touched it there in the VE table. Regardless of whether the wideband is hooked up. You're getting there with very little RPM, which isn't right. Do you have a leak?

Your timing is pretty low in the middle to upper kPa range and at a higher RPMs.

Your base airflow is likely high.

I don't have a leak. In fact I just took the manifold off and replaced the gaskets under the manifold. Everything was perfect, and I plugged off the evap system, replaced the hoses for the pcv and everything. What could be going wrong?

Set your PE delay rpm to zero and the enrichment rate to 4.

When you run with those changes, it should suddenly be very rich. If it is, then change your PE adder to 1.17 across the board and try again. You should end up around 1.15, but you'll want to sneak down on it.

You need to stop and take a breath and go through the basics. Check the plugs, do they all look lean or do they vary bank to bank. Check fuel pressure as mentioned. If you are so confident in your wideband setup, how about sticking it in the passenger side O2 bung since you said its in the driverside. Who installed the cam, is the pushrod length correct?

Plugs are perfect. Just normal wear and tear. Light tan around the diode on the ceramic. I installed everything. Checked p2v of course. Everything was perfect. I've already checked the passenger side. I have yet to check the fuel pressure. I'll do that.

I did figure out that I was blending the SD and the MAF tune instead of using one or the other. AND unfortunately, I mixed up numbers when comparing 2 tunes. The VE is WAY off and I just updated it. Working with a member on a couple other issues but I'm sure that the VE was the majority of my issues
