Use the definitions attached to the op and the lists of tables.

Why hasn't there been a "official" release by Shiv for new AT maps? Thank you for all your hard work!

All that's needed to tune your car is the tablet and the OTS base map, and that's what they sell.

$$$$$ and time
For $500 your getting flashing, logging, big gauge display and tunes for NA and turbo and SC for almost all rom types E85 and 2 grades of petrol and soon track data.
And you can de marry and sell the whole system

Their is over 140 roms if you add the options of even 2 or 3 tweaks that blows out the roms to over a 1000 as not all people like all the tweaks eg some like loud cold start some dont.

We are lucky the tunes are open and can be tweaked.

haha you're right.

I wouldn't even know where to begin (tweaking with oft tunes) lol

I believe this has been answered already but would this new E85 tune for AT work on CAL: ZA1J700D
...is there anything else that one should know about my car to be able to match my car to a tune? I don't want to brick my car....doesn't oft prevent the user from uploading any tune that would brick your car? I love the oft e85 but it really sounds like you took a great tune and made it better!

(Side question) I've always noticed this when I re-flash...the tune always seems stronger in the beginning, then over time it feels like it slowly loses some punch...maybe just all in my head lol.

Thanks guys

PS: I don't have any mods besides a drop-in filter lol...and my car is an auto.

Yes your 700D tuned OFT rom is actually a B01D rom internally so unknown to you your actually running latest factory rom compatable with your car.

you would have to open your calid 700D E85 rom with the oft 700D def and olso open one of waynos altered roms loke A01I with oft A01I def and transfer by copy and paste all the changed tables to your rom.

The main thing we have found that effects tunes on differet cars is maf scaling their appears to be a three slightly different maf sensors which can result in some cars running richer than optimium on E85, or if you have aftermarket intake.
This maybe what you are experiencing as the fuel trims learn it get a bit too rich loosing a bit of power.

You would have to log your tune on som full throttle runs from 2000 to redline and look at the AFR if its down in the low 11 range then that likely your issue your rearly looking for afr in the low mid 12 (12.3-12.5 ) range full throttle higher rpm. NA

Steve has romraider tips thread, with the exception that you use the defs and screenshots from this thread to compare.

You need to log the existing tune first to see what the car is doing.

My car ran totally fine on Stg1.
12.2 - 11.7 AFR.

I started getting an IAM as low as .45 after using @Wayno's tweaks and 98 Octane tune with my 91 Octane gas, so I started trying to learn the easy way to back off timing. The answer isn't easy. So instead, I started looking for a lower octane map, and found wayno's v33 flattened maps from when he was just getting started adjusting timing. The flattened map pulled as much as 5 degrees and yet, my car runs better above 1.0 load then it ever has. It seems too much timing is a bad thing. It's a bit more sluggish below 1.0 load, but when I open it up, it really takes off! I know this isn't the right way to adjust timing, but it certainly was quick and easy.

You want to find out where the IAM is dropping to locate the problem areas. If you're running different AVCS maps its likely the timing maps will need to be different.

Using vgi's tool with a couple of added columns and formulas its easy to diagnose what the cause is.

As@Kodename47 said find where the knock is. wayno did some specific mods to load limits to correct some issues he had and also to maf scaling not sure they will be applicable to all cars their is some variation in maf sensors, mine is heaps different to waynos andd i dont need to change the lower rpm load limits as he has done. it can make you run lean, not sure if that was done on petrol tunes like in e85.

They've been tested on a few MTs with E85 and AT with petrol. Petrol produces lower load so it's fine. It's more to do with what Kodename's said with avcs. I've seen a car with intake spacers which screw the top end pull -5 deg timing without dropping the iam on that timing map.

If you're on 91, why wouldn't you start with the 91 map?

yes that likely issue

[KoolBRZ]

I have the Skunk2 Intake without insert, 3"+, so my maf scale is quite different. Since everyone says the 98 Octane fuel there is equivalent to 91 octane here I started with @Wayno's 98 Octane map. I'll have to find his 91 octane map and try that.
