You guys are awesome!
I got it working decent enough for hot temps (>70°C). It is a little over damped but that is ok for now as I do not get those annoying drops that like to stall the car when I take my foot off the pedal.
It was idling higher than I thought it should be when I enabled PID and the IAC int value was very negative. It was idling about 50-150rpm higher than without PID control. The engine temp may have increased. I assume that VEMS will scale the iacv % in between the temp ranges. But does it do this after your peak temp? These cars apparently run hot... VEMS says its about 100°C, stock gauge says 80°C, and I double check with infrared and a probe on the tstat housing which both said about 100°C. I haven't tuned the cell before my highest temp and it is lower, so if VEMS continues to scale it would have been opening my iacv.
I will upgrade eventually, but I am trying to take it slow and learn one thing at a time. I looked into it (and tried it) a while ago, but there wasn't an easy way to import my settings and maps from MS to VEMSTune (at least that I could find) so I just gave up and figured my problems were more my lack of understanding rather than an older firmware version (which was true). But I also know that a lot of the code got much better and there are a few things worth upgrading for (idle, acceleration enrich) but ill get there.
Thanks,
Jim
