You are in UAE. I'm in DUBAI, we should meet and compare notes.

engine shake may just be the lope of your cam.

Im not sure how your timing table should look since i had some one else do mine.

retard - you want to get that whole table to be all 0s. Do this by removing as many degrees of timing as you have knock for that area. ie 2* from 1.8x.44, 2* from 2.0x.44, 1* from 1.8x.48

ltfts - all looks great in there. your car is running exactly where it needs to be. + numbers (red) are lean, - are rich (green)

stfts - never really care about these, since they just keep your ltfts in check. if they stft stays consistent it will load that as the ltft and then will start checking again.

a/f - im not sure how the narrowband info converts, but since your ltfts are in line, i dont think you need to mess with them.

I think it's a little suspicious that your ltrims and strims are all 0. Did you log in open loop, or is your tune just ridiculously perfect?

if i would have looked @ the table i would have noticed that too

have you changed any of the default logging parameters? (shows in the table display of the logger). sometimes if you change it, it will cause your data to log incorrectly.

Well...I hate to say it, but all his actual AF ratios look perfect too. Other than crappy timing his fueling looks disturbingly perfect. But that AF ratio...it brings a tear to my eye....I wish I could get mine to do that. That car could not have been tuned by human hands...

Another_User

Aha...I just realized something. No PE on that. Imagine how lean he would be at WOT...

Isn't narrowband inaccurate for A/F?

It's almost like the o2's aren't operating at all and it's just reading the bias voltage of 450 mv.

Yes, but they're accurate enough to tell that there's no power enrichment going on at 450 mv.

Another_User

I just thought something totally stupid, but....do you have O2 simulators? Like...what would they read if they were plugged into the front O2 plugs. Anyways, that vehicle is completely in limp mode (in more than one way), it has to be.

This is exactly what I was gonna write. There's no way that his A:F is actually right there. however it's still suspicious that the sins would even be that perfect, as theyre supposed to generate a random voltage centered around 450 mV, no? Even with o2 sims, you should have some STFT movement. I dont know what could cause this, but I bet you disabled something. Check in with the hptuners guys on their forum, as theyll probably be more familliar with your holden.

if this is an early model commodore, then it came from the factory with no cat's and no o2's, and will run in open loop.

what problems are you having specifically uae ?

Please post what you having trouble with and I will do my best to help you.

to tune your car properly, you will need the use of a wideband to moniter your air/fuel ratio's.
