ECMlink 2nd gear wot log shitty timing... why?

[habitatguy187]

I just set my base timing (had to advance it actually)
No boost leaks
fic 850s
e85
42psi base fuel pressure

Took the car for a run and the ecu pulled timing like crazy once i went wot. Before correcting the base timing, car would see 16-18 degrees full timing during pulls. What gives?

Because you zero'd the timing slider now.

This is from your clutch cut thread

I'm not a pro but here's what I'd do.
Fix your tps and throttle position. TPS should be .63v at idle and 5.0v at WOT. Throttle % should be 100% at wot and 0% at idle.
Zero your fuel and timing sliders.
Pull some timing.

Do a WOT pull. Let off if you get knock.
Adjust your MAF slider so your afr's are clean. Keep the cells as smooth as possible.
Once that's accomplished and you have no knock, then start adding timing. You can use the slider at this point, and when you're done, move them into the maxoct table.

She is running pig rich above 5k. Your AFRs are very rich and not following the commanded 11:0

Well, I tried leaning it out a few pulls after this and it just seemed to run out of steam and not pull as hard. Was about 11.1 afrs during that pull and it showed 2.5 degrees of knock. Also lost 40hp according to link... felt like it too haha

I guess I'm just uneducated. I thought that the ecu would add an advance on its own and that the sliders were used to add even more on top of the factory advance? Thanks for the help guys. I truly appreciate it

It’ll use the maxoct timing map as long as the fuel is up to par. If it think you have crappy gas, it’ll us the minoct map. When you use the slider, it will add to that number on top of the cell being using in the table.

Are you talking about mechanical or ignition timing? Ignition base timing must be at 5* BTDC

I looked at both Min and Max maps and it looked like sometimes it was in one and then another. I forgot to look for the interpolate check box.

You would take the timing on the sliders and add it to the timing map then zero the sliders out.
