Title: US 131 Dragstip 4/6/19
Post by: donky4444 on April 07, 2019, 08:19:26 PM
Hit the strip yesterday and did fairly well. I feel she has another tenth in her. First run other than my red light I spun off the line and it hesitated on the 2-3 shift. Second run no wheel spin and I manually shifted to 3rd to avoid the hesitation and picked up a few hundredths with a slower 60ft.

The hesitation on the shift has me puzzled. It's been doing that the last week or so when WOT. I reflashed my tune on Friday thinking that would solve it but it didn't. I'll need to try going to stock and seeing if it still does it. (https://uploads.tapatalk-cdn.com/20190408/65e8f96ba25146e1cc4ce0d617b166eb.jpg)

Good run there Don! I would avoid reflashing PRIOR to any Track event as the AFR needs to relearn it's values. Z

LMS v11 93 octane 3 bar tune. I mixed 2.5 gal of e85 to a full tank of 93 and ran it down to a 1/4 tank. Tire pressure around 28psi.

I'm figuring the same, that it's tune related. I'll know for sure once I go back to stock and try it.

Solid runs!  You may need the latest revision since there was an issue with that version of tune for some other people.  Does this describe your issue: https://shoforum.com/index.php?threads/lms-3-bar-v11-93-bounces-off-rev-limiter.138591/

That's exactly what's going on. I guess I'll email them today even before testing it on stock tune.

I emailed LME and they sent me a revised tune this morning labeled as v16. I guess I need to pay more attention if Im jumping from 11 to 16. I'll install today and see if I can get a wot run in. I doubt I'll make it to the track today to test it.

You should see a pretty big difference now if you were 5 revisions behind

V11 has fuel pressure issues regular 93 octane...
Mix in a couple gallons of E85 and it's gonna exaggerate the issue...

Good luck with v16!
