Thanks Jayme, It'll be a couple of days before I can do this. I think I tried this a few times in the last log(jeep61.2.xdl) it may have what your after. If I was to adjust it, what should it be altered by?

Done a quick update. Modified the VE off log2 and done some smoothing as the wide band readings were a bit choppy.
Log this one and post up 1 whole log from first start to finished even if it's a 1 hour log.
A full throttle run from idle to limiter would be good.

Looks better than some of the earlier logs so there's definitely progress.
This 1400rpm spike almost looks like a mechanical design problem?
Cant pin it down to anything in the tune as yet.

How does it run and feel compared to the Jeep tune?

Thanks mate. The other bin needs a bit more timing, it feels a bit flat, which is one of the issues I had with the oem Jeep tune, you have to bury your foot in the throttle to keep it going, which I imagine is to get the emissions correct. Using my obd scanner the Jeep doesn't use timing much over 35° at cruise, push it up & it cruises along much better.
Once we get on top of the lean spot, I'll put it on the dyno to optimize the timing etc.

Well that's a lot of timing for petrol.

depends on the engine... ecotecs use hardly any timing at all, wheras a VL turbo cruises along at 45 - 50 deg advance in places!

What about at full throttle? 36deg at 100kpa is a lot. That's methanol range.

Bit more timing on this one

ok see here, from jeep61.2.xdl
look where you push the throttle open at 7:03 and it goes lean. then while maintaining a steady RPM and MAP, the wideband slowly comes richer. that tells me you need lots more AE (like the throttle pump in a carby) there are loads of lean spots and some of them are VE a little lean but a lot of them are right after you open the throttle and are caused by not enough AE!

as for the timing ... its only 8.8:1 compression, ive seen engines with similar compression with 36 deg+ timing at WOT on petrol. all depends on cylinder/head shape etc. I wouldnt be surprised if thats the timing it needs.

I put sone more AE in the last bin. But i didn't look at temps to see if that effects this motor.
Possibly may beed a longer decay time as well.

Thanks Jayme. So as a test should I add say 10% to the entire AE table or at the 800 & 1600 cells?
Dylan, thanks for your time, I'll see how I go for time tomorrow, I have to pick an engine block from the machinist tomorrow before I go to work.
