log was third gear, believe yours was fifth ?

have tried to reproduce in fifth up to 5000 rpm full throttle but could not produce issue on my car with our fuel which is guaranteed 85% ethanol e85. on A01G rom UEL catless header, will also pull at 1500 rpm on road.

dont have dyno

again not saying it does not happen just that it does not appear to be a universal problem on all cars.

also my current tune is modified to suit my fuel maf scaling OL Fuel Table adjusted, so I am no longer a true test.

however log posted previously was on stock car running standard oft tune on E85

I have a road I can log this on. It is privately owned and I have permission to use it. I have been able to reach 125mph before tuned. I am now tuned, on E85, with OFT. I am running the stg 2 UL E85 tune since I do not have my header yet.

I have to rescale my MAF first though as I got a new drop-in-filter.

I have a lightweight crank pulley, drop in filter, and cat back exhaust, so not the same exact parts but the tune will be the same, hopefully.

@ck-GT86 You did mention you got a header, but was that after your first dynos run or before, I forget your time line. Where you on the EL or UEL tune?

I will be getting a header in a month or two and will be able to compare then if you were on UEL.

I have a lot of respect for both tuners in this thread, and I am using one of their products, but I hate how it always happens like this, one tuner pointing fingers at the other, and then back and forth. Lets put our heads together and find a solution instead of blaming someone else, for something that may or may not be related to what they do.

I have a car I am willing to run, and would like to hit a dyno, so lets stop playing who's **** is bigger and lets figure this shit out

I got the P&L EL header long before putting my car on any dynos. And I used only the Stage 2 EL maps since, never bothered to try the UEL maps. My headers are also catted, don't know if that'll make any difference.

I am not aware of the dip being recorded on any other single dyno, let alone dyno type, than the one at Mann. Then again, I haven't ever seen anyone do 1 minute long dyno pulls.

I just wanted to know what tune you were running. If it is a tune related issue, the header should not make a difference. With the P & L you ran the UL tune file, which is what I run now.

I will try and get out this afternoon and get a log to rescale MAF then I can log a 0-1?? mph to capture 4,000 through 5,000 revs.

Hope I have enough road haha

dear steve
at wot your log shows alittle lag in CL/OP transition.
do you know why?

Was not logging cl/ol in that log. are you taking about arround 3v maf ?

It was done on a road that was slightly uphill and does change gradient and has the odd bump like most roads.

were looking for a fairly significant dropoff in torque/acceleration similar to what happened on the Mann dyno. around 4500 rpm under high loads.

i point to the time region between 41-43 that 2 seconds pass for going afr from 13 to 11.25 .

i think this means a lag for CL/OL transmition.

Honestly don't know, but not seeing a decline or flattening of rpm increase or decline in engine load or ignition advance ect which would indicate the massive torque dip the guys in this thread are looking for

Did you meet with the guy in LA over the past weekend? Was he able to show you his reported dip?

Sometimes testing for all possible conditions makes for an extremely reliable tune. We tuned for 30 second pulls Ken Blocks Gymkhana 1 and believe it was well worth the effort. Being able to bounce off a REV limiter at 30 pounds of boost for 20 seconds at a time...

I don't want to add to the OFT vs EcuTek debate... But I've had headers + op + Flexfuel installed - with Ecutek and a Delicious tune.

I really could not be happier. Delicious and my local tuner had various logs/tunes/voodoo done. Got the car back... It felt great, but got a call from the tuner saying "don't push it as its running a tiny bit lean". Took it back, 15 mins to reflash and retune and relog... Everything is now 100%.

The launch control and flat foot shifting etc is all really 'unnecessary extras' but 1) damn they feel cool and 2) I don't 'need' a sports car either... I could get a sh*tbox to get to work and back ;-)

More expensive yes. But in my opinion... Worth it. Top quality work + reliability etc.

Again, nothing against OFT, and I can only recommend on my personal experience. But Ecutek and delicious tuning for the win!

Man, that is some awesome driving.... Great video (and oh how I'd love to get a ride in that or any of his other beasts!)

What Load percentage were they running on the OFT Dyno with the Dip?

I do remember have a "slight" hesitation right around 4500 rpm in 5th and 6th. It only happened when going up hill at WOT on particularly hot days. Looks like a knock pulling back timing to me though

Stg 2 Beta:
DataZap Log

Edit: I also noticed in the OFT video, he short shifted 3rd into 5th. In the Ecutek video he goes in to 4th and then 5th. Although not a big difference.
