Thanks for the heads up- I'll update with a summer link! That tune was for winter blend

I have the borla uel and trd airbox. I am running the ots stage 2 93 map. I am considering buying th gs intake if there is a map for it. Is there a map available for gs with uel on 93?

Hello....anyone make a map for 93 octane?

the maf scalling difference between stock intake and grimmspeed are very small, you will be fine with grimmspeed intake and ots tune.

you can always make it better with custom scaling though.

I guess that was my question; is there a map with custom scaling for the GS with uel on 93?

if you have an oft email the openflash guys and i think they will send you a grimspeed intake map

else just do your own maf scaling

The only difference between Stage 1 OTS and Stage 1 Grimmspeed is the MAF scaling. There are no other fueling changes. So if you get the Grimmspeed file you can just copy its MAF scaling into whatever ROM you want.

If you want, shoot me a PM. Going to be on a plane most of the day headed home but I can send you the file this evening.

I guess he is looking for stg 2 tune for grimmspeed since he has UEL header.

Someone correct me if I'm wrong, but it seems that MAF scaling is best option for those of who runs stage 2 ots.

I re-scaled my MAF for the GS intake on my stg 2 tune. At first I tried copying the MAF from the stg 1 tune but it had LTFT off by 6%-7%.

anybody has a scaled stage 2 uel file working with a grimmspeed intake?

Good lord people the only difference between a standard tune file (at any stage) and a Grimmspeed tune file is the MAF scaling. It's not hard to put that data in yourself once you have Shiv's Grimmspeed stage 1 tune - you just copy the MAF scaling table using ROM Raider. Again, this works with any stage tune file. There are no fueling changes, no timing changes, no code changes - doesn't matter EL UEL 91/93/E85 - changing intake only means changing MAF scaling, which is what I would provide if asked as I previously stated.

I would rather listen to below two reputable people's comment than your comment.

Maf scaling is not the only difference between stg 1 and stg 2 tune. As far as I understood, it is not ideal to just to copy MAF scaling from stg1 to stg2.

You seem to have a problem understanding English. The only difference between a Stage X tune and a Stage X tune PLUS GRIMMSPEED - IS THE MAF TABLE.

I'm not talking about differences between a Stage X tune and a Stage Y tune!!!!!!! I know there can be SIGNIFICANT differences between Stage X and Stage Y.

BY WAY OF EXAMPLE...Start with a Stage 2 UEL 93 tune (i.e. Publicly available 2.067 tune from OFT site). Copy over the Grimmspeed MAF table from the tune Shiv made (this is a stage 1 tune but YOU ONLY COPY THE MAF TABLE GET IT). You now have a Stage 2 UEL + Grimmspeed 93 tune. It's that simple!

I swear with some people it's like talking to a wall...

Believe me, don't believe me, whatever.

Here's the tunefile that Shiv created for 93 Octane B00C Stage 1 with Grimmspeed. Again, I did not create the file linked below, it was provided to me upon my asking.

You can take this and extract the MAF table and use it in whatever tune you want, or you can keep being obstinate and believe that there's something else that has to happen to make this useful. Your call. I'll tell you though that I also am using the MAF table in this file in the latest tune Shiv helped me out with, which was to create a Stage 2 93 EL Tune specific to the PTuning header - in other words, many peoples' holy grail of tuning right now. I'd be happy to post that one up also if I was asked. Just like I would have done with this one.
