Unrelated: anyone dyno stock vs open flash stage one 1.5x with drop-in? Been researching for months but don't recall if I've seen this.southern dyno would be best

This was 1.55 on stock car (3,700 miles) with an HKS drop in filter. The baseline I took a stock rom and set the IAM to 1.0 turned LTFT off and made both high & low det cam cables identical and ran 2-3 runs on each map to verify consistency.

Stock - OTS 1.55 - Custom dyno tune



I don't remember even looking at the logs, but iirc the later runs on the 1.55 started becoming richer but I had flashed it after doing stock baseline so trims did not settle. The dyno tune didn't have LTFT set on WOT. I don't have any from having miles on the car for LTFT to kick in.

If you could briefly summarize, what were the changes you made in the custom tune vs. the OFT 1.55 tune that resulted in the slight improvement?

Thanks for the massive info. Could you tell me which line is the oft original?

Just flashed the E85 EL Stg 2, have a Perrin intake + silicone tube. Could someone take a look at my numbers quick and see if everything looks ok?

Edit: Car feels great.

Actually it was a completely different tune that I made my self for a friends car. I just did a few small tweaks and did a few pulls to see how it did. I just didn't have the OTS vs stock plot otherwise I would have posted that. The difference in power was minimal. Remeber the OTS are generic one size fits most so it's not pushing as aggressively as the tune posted above as that was a tune for one single car.

Thick was the tune I made. Thin was OTS 1.55 dashed was stock.

I am very impressed with your results. Awesome gains across the board. From this it looks like stock was about 138 hp peak yes? Would that be around 168 on a dynomax?
EDIT: Dynojet.
Was my brain is fried today lol

I want to say it was ~136. I have the baseline somewhere. Stock cars on this dyno run 125-135WHP. I have seen drop in filter cars doing ~130-135WHP on average. Hence why I try to tell people look at the % gains. As for my own gains on that car was just a hair under 15% @ peak power, and the largest power gain at 7,400RPM at ~ 25%.

I am sure the OFT e-tune service would give similar gains having a tune dialed in for a specific car. That graph however can get you an idea of how much a shelf map may get (fresh flash, no learning, but AFR's were pretty much within 0.1 of target which should yeild similar results if your AFR learning lands near target) vs a dialed in dyno tune.

Was just watching Vishnu videos and learning how to go beyond just flashing OTS tunes. Would like to at least learn how to turn on and adjust LC

Comparing an off-the-shelf tune (designed for the lowest common denominator) to a custom dyno tune should (nearly) always show positive gains. In my limited experience with Vishnu's work (just the OFT), I've been happy with the care Shiv takes to be cautious and tune for the worst case scenario.

I've paid to have a previous car pro-tuned (call it what ever you want) on a a Mustang dyno with every precaution taken for every change made to that car (not my 86, yet). I always felt it was worth it, but not everyone has the time or money to do so. For those people, the OFT and Shiv's off-the-shelf tunes represent great value. My "old" (based on a Subaru 2007 Spec.B) had WELL over 100 dyno runs. My 86 will be lucky to see 20-30 pulls, no matter what I choose to do with it.

Bottom line, off-the-shelf is adequate for 90% (or more) of car owners out there. If you crave that extra bit of performance and driveability, then you should absolutely eventually get a custom tune. But most people will be well served by the value of the OFT and Shiv's hard, thoughtful work.

Yup I agree fully. As long as your target afr and actual afr are lining up after trims come in the majority of the gains are had through the OTS maps. Unless you are drifting away from the exact part the OTS maps are designed for most of the cars line up pretty close and need minimal changes.

Yes the 1.55 stage one is excellent. I guarantee if Shiv tuned the twins for Toyota/Subaru before releasing them all those "only thing wrong with car...."reviews would never exist.

That is why I said elsewhere that with the Stage1 tune, I think there is a good change the FA20 could win Ward's 10 Best due to its efficiency, technology, power, and refinement. Unfortunately it is really lacking in the refinement department.

http://en.wikipedia.org/wiki/Ward's_10_Best_Engines

Edit: It looks like the FA20 won for 2013 lol. It would have been higher on the list though. Our Grand Cherokee has that Pentastar 3.6L which is on there multiple times and for as fantastic as it is, I still like the FA20 more.

Imagine a long narrow empty balloon. Apply fingernail polish to one small spot on one side. Let dry. Blow up balloon. The nearly 90 degree angled balloon you now have is what the general practice physician's unmentionables looked like.
