Clutch slip even if im in 3rd gear starting to do pull at 2500rpm ish? You are right thought wheels dont spin just overboost and then limps down.

Yes, clutch has the greatest tendency to slip in a low RPM, high load situation - e.g., in the higher gears when you start a pull from low in the RPM range, right when you first hit full boost. Take a look at some of the clutch threads and you should see similar things reported from other users who start experiencing it. I wouldnt doubt if you saw it in 4th gear as well, it might even be worse because of the lower mechanical advantage.

45k is not a ton, but also not low, especially if the PO was launching a lot or doing fast shifts with the stock CDV still there.

I'm gonna do a v6.4 e30 pull later tonight and see what it does/ log also.

That new update got some nice power behind it prolly like you said it's slipping.

I told them ill flush my fuel tank with a few tanks of 91 to start fresh and will log e30 in a few weeks.

Well your clutch won't slip if you start wot at or above 3500rpm, maybe they want u to do that to help verify that your clutch is slipping. But... your clutch is slipping, the new map has too much torque for the 6mt clutch unfortunately.

That's probably why when I'm on v6.4 it drove so much smoother, with no issues.

Somebody brought up that the V7.0 was developed in the 8AT. Any thoughts on that?

Anybody here a 6MT that has no issues ?

Doesn't really matter which tranmission it was developed on. If the tune is making too much torque for the stock 6MT clutch to handle, it is going to slip.

Makes sense! Thanks for your input and help. I can definitely see now what you mean by them asking for higher RPM pull to confirm slipping clutch or not.

I'm gonna do some logs on the V6.4 in a bit hopefully show some data on why this one works compared to the V7.0

Here is V6.4 stage 2 e30 (same tank )

The fall off isnt as hard as V7.0 but it is there ( see log )...

Thoughts? The more I think of it now clutch slip....

ctt300 · 01-07-2020, 12:12 PM

I agree on the clutch slip. Logs look good otherwise and that explains the funkiness of the v7.0 logs from yesterday. Do you have an upgraded intercooler and catless/hi-flow catted downpipe?

Yup catless Downpipe and upgraded intercooler also!

Well I'm pretty sure if they did all the beta testing and developing of the ots maps on 6mt cars they wouldn't throw so much torque at it to cause clutch slipping issues in most 6mt cars so ya it does matter. The 8AT can handle more torque it's as simple as that, wish they would make transmission specific tunes to accommodate this known issue.

Nothing wrong with these logs. Seems the new version of the ots map just has too much torque down low for your clutch to handle.

6MT here. No issues with the clutch slipping on Stage 2 93 octane. Adding some corn today and will flash to the Stage 2 E30 map and then log. We'll see. If anyone would have clutch slipping issues it would be me. I have over 77,000 miles on stock clutch.

Halim sent me a test map for e30 this morning! I did (Well I'm the idiot who prematurely pulled the OBD2 plug and closed my laptop before the log saved) logs last night on stage 2 ACN91 V7 and it went smooth as butter no issues!

I think the e30 V7.0 just had too much and wear on my clutch same time. I'm gonna try the e30 tester Halim sent me when I finish this tank !

JaredG_F30 · 01-08-2020, 01:07 PM

Just logged the E30 map. I get a boost spike, throttle closure and my HPFP crashes mid-range. I've asked PTF to review. I'll probably switch back to v6.4 until I burn down to 3/4 of a tank and add some 93 octane to reduce my ethanol mix to E25 and try again.

Hey! Same thing! lol TWINS!

YAY for us...lol

BTW I didn't notice any clutch slipping.

thats the weird thing how everyone told me it could be clutch slip... but i know how that feels i doubted its that at all...Im all ears so didnt want to disapprove that. Ill try the e30 tester map probably when I get to half tank so I can mix and see what happens! Could be a combination for me being starting to wear down clutch + mapping is too aggresive for 6MT.

No issue on the V7.0 acn91 on my end BTW.

Try to reproduce/log the same conditions as before where we saw the disconnect between engine RPM and engine speed. Most importantly start at low enough RPM in 3rd/4th gear and go to WOT quickly (dont roll into it).

I know that clutch slip is usually very tangible in the sense that you can hear RPM shoot up and feel acceleration drop when it happens, but i think the slip in this case is minimal so the car is still accelerating hard and it grabs again right away. Again not saying 100% clutch slip but it was my best guess based on the log data.

agreed ! I need log again on the same map after I do a 91 flush to reset ethanol content. There are times when the rpm shoots but doesnt move (like a clutch slip) but it was never consistent maybe 1/10 pulls. Im thinking due to the new power band and possibly worn down clutch Im having e30 issues....

The ACN91 Stage 2 V7.0 was smooth as butter last night I wish the logs saved....

Fuel pump crashing in all 3 logs, massive overboost that isn't being caught and controlled bi throttle closure in all 3 logs.

ok perfect that exactly what i thought of when i ran them. Overboost then fuel pump crash to 1800psi.

Ill go ahead and log V6.4 tonight and compare.

thanks again for all your inputs Im slowly grasping this datalog education.
