OFT - Example alternate maps for AT, 98RON, E85, MAF Scales

[Nah]

Lol thanks I'll try it out soon and get back with results...!

So, after dialing in my cams and timing ive noticed that my my afr went from 12.5 to 13.0... right at 4k to redline. 2-4k follows commanded perfectly. I'm gonna keep playing around with it... but with the increased flow what do you guys suggest to get my AFR's back to where they should be?

Increase MAF scale or add enrichment in the fuel map.

[Nah]

alright so after further fine tuning, my e85 tune is near complete thanks to wayno's base!

Anyone have any tips for tip-in... I've made the changes steve99 has recommended and have full DI in loads .1 and .2. this helped. but its still off slightly... its like a slight jerk... rpms go up and down every so slightly... then right after the pedal feels perfect.

Thank you

Some data to look at.. any help is appreciated thanks!

looks ok

should rearly log iam and ignition advance rarther than vvt intske\exhaust

how long after flash was that log higher band ltft is 0 so maf scaling either rarly good or its not had much closed loop time in upper band

it look like it might be slightly rich but a few more miles may see negitive fuel trim and that will sort itself out

What is the reason, why the Timing Compensation Per Cylinder A and B are modified and C and D not (within the linked v111.2)?

some cylinders may run hotter than others due engine design , coolant flow exhaust design, and hence may be more knock prone than others.

the stock maps have this as well but maybe different compensations

I did not check the stock rom, but the OTS maps did not have it.

In general you are right, but is this a common rule which can be used for all the different EL or UEL (in my case) headers?

shiv initially zeroed them all out in the base oft tunes, i think he put them back in in the latest ofh specific maps.

you would rearly need to be looking at individual cylinder knock counts to make your own specific tables, i suspect waynos are based of the ofh specific tune

You've got it reversed. Base tunes had them, OF tunes had them but reduced, and OFH-specific tune had them removed.

ok thanks , was too lazy to look thru all the tunes, just recall they chaged it round a bit

[Nah]

Love this group

@Wayno I PMd you about the donation for the link. BTW Is there a way to do AT Launch control yet
