Lol. tough crowd around here. Just was trying to prove a point. The power band is less than ideal in many respects and a certain shift point would be ideal under many circumstances. This car sees track too.

Retuned a car GTS car i had already tuned as OBD1 after converting it to OBD2, no other changes. S50, 3.5" MAF, 24lb, Ebay Headers, BW race exhaust.


Retuned a OBD2 S50 swapped E30 M3 that had a TRM off the shelf flash on it. Has some weird aggressive cams in it that were doing some crazy stuff. Didnt make any power though?

Tuned 2 E46 M's.
First bone stock:


Second 214k, stock intake with aftermarket headers/full exhaust

Progression!

[328ijunkie]

Tuned a GTS racecar today. Fresh S52 Build, M50 manifold, Headers, Stock cams with timing tweaks, BW race exhaust. 3.5" MAF had to get slapped on at dyno as stock MAF maxed out at ~6500... Stock Injectors. Was running M52 stock tune when it first came in.

nice S52 #'s Dave ^^^

i gotta get you guys to remotely flash my ECU once i convert to a M50 manifold :up:

[328ijunkie]

Look forward to it :)

[328ijunkie]

Few Notable Updates. Retuned an earlier E46 M3 after adding headers
Pre/Post headers, no tuning changes


After Retuning


Progression: Stock Tune, Tuned, Then Tuned with headers


Also retuned an Alum block M52 E30 after it got headers/a nicer exhaust setup

I have to say, I'm VERY impressed with the thoroughness of this tuning.
I think you'll have gotten a client out of me for sure.

Thanks! Look forward to working with you. We try to pride ourselves on transparency and backing our work with data vs most of the competition :)

Retuned a Schrick cammed, M50 manifold, shorty header, AA track pipe, HPDE car. Had 3.5" MAF/24lb injector, Schrick conforti tune on it already as the baseline.


Also fun fact of the day, changed on the dyno from a 3.5" MAF reducer and the stock ASC intake boot (with ASC still in place) to a silicone 3.5" to 3" smooth intake boot. No tuning changes...

Thats pretty significant! Im not sure what the ASC boot is, but Im guessing its the original rubber one.

Are you saying that the aftermarket part lost 4 HP on the top end?
Interesting.

[TheAxiom]

No, it gained power.

ASC is the traction control throttle body system

http://www.bimmerforums.com/forum/showthread.php?984257-E36-ASC-Delete-DIY

basically there's a SECOND throttle body in front of the main throttle body and the intake boot that goes from the MAF to the ASC Throttle is shorter.

Deleting the ASC throttle body requires a new intake boot.

I'm half tempted to do the ASC delete myself... I have an LSD and snow tires after all.
