And entirely unnecessary on a DD car....

An air to oil is too much for a DD car and a factory type unnecessary, how can you protect your engine in Greek summers at 40+ Celsius degrees?

Unless you track the car or do extended mountain runs then it really should be a non issue.

One of the good things we still have in Greece are the very good and empty mountain roads with no traffic and no police radars, my favorite one:

I prefer the slippery downhills where power doesn't matter as driving technique, suspension & brakes are first priority in the "to do" list!

So I've opened the Stg 2+ E85 v4.03 bin and noticed that the Ignition Timing Post Start table already has all of its values set to -15.08, rather than the 0.04 value found in the 91/93 tune. Is there a reason these two tunes are different?
I was going to edit the E85 tune in order to keep the loud cold start, but it seems like it has not been changed.
Thanks!

Don t know why they kept it at -15, maybe it *could* help with cold start on very cold days, to warm things up faster?

if you want it louder , make it -17 o -19 and increase the first 2 rows of the 2 tables "maf corrections after start" and maybe rise idle rpms a bit

I have the Stage 2+ w/ UEL header and have noticed now my throttle is not as responsive (going from stops requires pushing the pedal further and this has also made heel toe blips harder and not as smooth).
has anyone else had this issue? I keep seeing that throttle response got better for ppl but not for me.


2015 FR-S, Mishimoto CAI, Gruppe-S UEL header, OFT v2 tablet with the latest Stage 2+ tune.

The later tunes have a more smooth linear feel to the pedal. If you are looking for the more off and on feel I believe the v2 tunes are your best bet. Also you will have a laggy pedal after first flashing the tune. Give it 20 to 30 miles and the feel will come back. The ecu has to relearn the throttle position.

I just noticed you have a cai. Your maf might need to be re-scaled as the oft tunes only support stock intakes.

I'm running the v3.02 currently on my 2017, and the redline seems to hit right at 7600 but then if I stay on throttle, rpms drop off all the way to 7200 before revving up again. Is this changed in the v4 tunes? If not, is there any easy way to have it stay at the cutoff if you stay on the throttle? It's very annoying on an autocross course if you have an section where you're on the rev limiter for a couple seconds.

V4 is a much better tune to run on 2017 plus cars
