OFT V4 Tunes idle issue - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Daily86 · 06-28-2020, 02:14 PM

'17 86 AT. OFT V4 stg1 & stg2+E85 tunes. When started and the engine is cold, idle is steady. When shifted to drive or reverse idle jump up a few hundred RPM. I had V3 tunes before and they didn't behave this way. After engine is warm doesn't do this either. Anything I can change? Besides getting a manual.

probably the cold start that got tamed in v4 tunes, maf compensations are different

If it runs poorly, it's because the MY17 files for black manifold 6AT just have the tables for 6MT red manifold.

Can you let me know how your MAF correction table look like? I had the same issue and after updating it rev will bounce a little after cold start in parking gear..

Thanks

I've been experimenting. This is what is good for me. Look at the link that Kodename47 posted.

I'm the op of that post.

Just want to solve the still existed one-time small bump, seems like the only major difference between mine and yours are the number "9" at last two rows. do you intend to put the 9 there or it just liked that at beginning?

Daily86 · 07-14-2020, 05:30 PM

Didn't notice that. Yeah, I think I did that. I've been using the table like this and doing fine. When I get a chance I'll try to change it to a 7 and see if there is any difference.

Forgot about this thread. I changed the "9" to a "7". No difference. I'm pretty sure I made those a "9" by accident.
