OFT Openflash V4 tunes released for 2017+ with Launch/FFS

[timmydatooth]

So today driving home my CEL came on. I checked what the code was on the OFT and it said p0420. This only happened after I updated to the new tunes. I was on the v2.076 tunes for a couple years with no CEL code ever. Do I just disable it on the oft and move on?

What tune did you use? It has been found that stg2 and stg2+ A01D does not have the deff for P0420.

This is my calibration code for my tubes <ZA1JA01D.ori> and I use the srage2+. So are they fixing this problem and will it damage my car?

It will run fine. If you have a catless header that will throw a code and disable cruise control.

my car is in storage right now so i can't test it, but i wonder if it could interfere with any new modification done to the V4 tune

It still works the same, I adjusted the timing tables the same as before and it all looks good. I’ve tested the stage 2+ 93 tune and the e85 tune.

I absolutely love my Open Flash tablet!

I flashed my '13 FR-S with the Stage 2+ tune (no E85 because I live in hell) and... it may be all in my head... but I swear my car ROARS now.

I recommend the OFT to everyone who will listen (and owns a compatible car).

When I first bought it, I only had a new exhaust so I was Stage 1. Then, I added a CAI and UEL catless header and moved to Stage 2 (2+ was years away), and now I'm stage 2+.

Each stage brought the same fantastic seat-of-the-pants excitement; like I got an all-new car.

Thanks, Shiv, and the rest of the OFT team - your work is outstanding.

I'm running OFt V2 stage2 on an auto 2015 frs. Love it. What are the advantages to the V4 tune?

Has anybody requested a flex fuel tune based on V4?

Sorry but I really don't know about defs and tunes too well. I just put them on my OFT and write them to my car. Is shiv and the OFT guys fixing this for the v4 tunes? Is it better for me to just switch back to the v2.076 tunes just so that I do not get that CEL to come on anymore? Just don't want to leave the v4 tune on if it is hurting my car...
