New Stage 2 UEL (91-93 and E85) OTS tune files

Improvements have been made to low end power. Specifically the very low end (under 2000rpm) where some customers have reported a hesitation with the current tunes. I have also revised the VVT mapping significantly to optimize performance with our OFH. The previous maps weren't nearly as optimized our header as we wanted them to work reasonably well with a wide range of UEL headers.

Top end power gains are also very substantial. Much of power gains come from revised individual cylinder ignition retard, IAT compensation and ignition advance b tables. In basic terns, the new maps will make a bunch more power when air temps are lower (under 80F). The older maps were a bit conservative in this respect. And since it's winter here in the northern hemisphere, it should make a lot of people happy

Please note that these dyno results were done on a customer car running aftermarket big brakes (front and rear), lowering springs/shocks and non-OEM tires. It was also done on a different (slightly lower reading dyno) compared to the dyno results of the old OTS Stage 2 UEL map. So even though power numbers (old vs new maps) are roughly the same, make no mistake that the new maps make a bunch more power as evident with the first dyno result (same dyno, same care, same day) posted above.

These new Stage 2 UEL maps will be available towards the end of the next week in *BETA* status. And only for USDM 6MT cars first. If all goes smoothly, we will be releasing them for USDM 6AT followed by ROW (rest of world) cars. I wish I could release them, for everyone, all at once but it's a pretty big job supporting all the dozens of calibration IDs

Have a happy Thanksgiving!!

Cheers,

PS. Our Black Friday sale started toady. See sig for details

Does this mean that non-OFH users should stick with the same v1 OTS UEL tune, or is it still beneficial to switch over to the new BETA tune when it becomes available? I supposed absent of testing with other UELs you wouldn't have a solid answer but I thought I'd ask the question anyways.

I'm excited

Very happy with my OFH+OFT glad to see this. Can't wait to try it out!
Interested in the beta as well when available

OFT/OFH user here on 91 octane, USDM 6MT. Would love to be included in closed beta or whenever this is available.

Do you think IAT will be more stable than older tunes on 91 also? I use tune 2.07 91 stg2 and my IAT can fluctuate down to .7's occasionally...

*IAM not IAT

any updates for BPB users? still on the beta flash for the BPB Stage 2 UEL 91 flash.

Can't wait to try this!

No worries lol. Have you tried tweaking your tune for cali 91? I think @steve99 has some tips and tricks that could help you out.

I haven't... but now I want to wait for this new tune to come out naturally. Have you done it, is it tough?

@Shiv@Openflash Shiv, any chance of testing out the new maps on E85? what kind of whp could we expect from it with e85?

Can u plz address if u will make similar tweaks for your OTS map for EL's. U have many loyal OFT customers that chose the EL route. I am hoping u r not doing this just because u sell an UEL.

Uhm, that's basically why he is doing it. He stated in his original post that he made his stage 2 tune in a way that would be compatible with other UEL's on the market. Now he's revising it for his UEL specifically.
