IAT spark not adding any timing

[pjs]

09 base vette, LS3, with A&A kit, 3.4 pulley, 11 PSI, with M15 nozzle Alky kit...

Runs good but wondering why IAT base table is not adding any timing, especially recently with cooler temps.
IATs ran as low as 70*F but no timing added.
Any idea why/where? Figure I must be missing something. Still learning...


Thanks,

Did you check the values in your IAT timing table?

Yep, edited the IAT base table to start add timing 86*F and below but not seeing it happen.

IAT mult table at 70F is zeroed out. Zero times any number on the base iat table = zero.

Interesting, guess I didn't think this table would need to be edited as well. Obviously it does. Should I set those cells to 1.0 to be enabled?

Depends on your target and the amount of spark you want to add.

Thanks, I will try that and let you guys know how it goes. Probably what ttz06vette meant by checking the IAT timing table. Sorry bout that.

Yes...meant to have said table(s)

[pjs]

That worked. Thanks for the help!

Had to back off the IAT timing a bit but worked well. This guy don't like much timing for some reason.

Anyway, thanks again.

With Meth I can run 16* up top at 16PSI no problem. One key I found is dialing in my meth activation curve. I ramp it in pretty early and set the gain to 6. It runs fairly rich at scout 10.8 AFR but no KR and good power.

Dam, guess I'm doing something wrong. Mine runs rich as well but meth coming on around 4 PSI. Centris being all top end, figured I didn't want the meth on too soon. Guess I should try it and see what happens. Thanks!
