no positive intake pressure till 4+sec into each run. have some driver and tbrake bugs to fix.

What did it run? What boost? Still on pump gas? Are you running Holley EFI?

pump e85 for the moment till we lean on it. then e85-r will be used. holley hp ecu and prodash. best so far has been 6.90 @107.8mph. did have a pass i went 7.00 and only ran 68mph. that would have been 80s maybe but didnt make any boost either. non of my passes has seen boost till 4+ sec into the run.
5psi but not till 4+ seconds into the run did it see 5psi. converter so tight right now. it just flatlines rpm once i shift. we fixed the transbrake, bump box and kill switch issues this friday. that was a major ordeal that has been holding the car back nog allowing a good clean hit. trying something different each pass had been uneventful. going to hopefully test on wednesday and turn it up little each pass. as i did not dyno tune the car. i didnt want anyone to know what kinda power it will make. kinda want the performance speak for itself. yet once i dip down to mid 5s or so. my et's may go dark. as the norm is 5.40s-5.20s for small tire class fillers. i dont want anyone knowing if i dipped into the 4s or not and many races wont allow anyone whos lit the clocks to participate for bigger money. its all a hustle at that point.

video above that i removed and uploaded a clearer imagary
Where are you racing?
I assume that's a glide? Do you think your issue is all trans stall related? Or possibly waste gates? Whats your target boost and what rear gear? Just curious.

Much better video. We finally got back to the track as Havana opened up. We were down there with a SBF turbo car. He drove it there and went 6.09 at 120 on pump 93 and 10psi. It’s gonna be a killer little combo. I’m still finishing wiring.

yes glide. not trans related. it was ecu related and now configured properly. had the tbrake set like bump box. so when i engaged the brake it acted like a bump box. it dont do that now. we commanded 5psi we got 5psi on the last pass. just didnt stay in the beams to get a slip. it picked up a bunch but we dont know how much. converter is pretty tight but not overly tight as we can get boost instantly off the line. but we need about 15+psi more to get high gear to make some steam to get rpms to climb on a pass. which is expected.

Glad to see you got this thing on the road man! Not gonna be long before you're making killer hits!

well it runs but it has issues unresolved to date. i think i have a bad engine harness from holley. as crank sync issue wont go away even with new sensors and extra shielding and distancing from other wires. non of my other sensors work either after getting new and redoing the ecu all over. nothing works as intended. so its parked and i could care less right now.
Nice 
Take a break, it took you a bit to get the car where it's at.
When you get back at it, everything will come together as you planned.
Sometimes we rush things and a break is needed to set our minds straight.

I’ve heard some rumbling on the forums about incorrect pinning on the harnesses. You might check that out on the ecu plug end. The diagram s are pretty clear and it’s easy to check. Has it done this from the beginning?

it runs fine for a bit. then turns to ****. i get rpm sync errors. sl showed a shitshow.

Sounds like it’s either cam sync or crank trigger related. Did you post anything on Holley’s forum?

yea all they wanna do is spell check and complain about how i type my **** out. rediculously and unhelpful as hell. as they chsnge everything i typed out and makes no sense to me after that. so i just quit. i guess i should type it out in russian and see if they wanna spell check me that way. jackholes.
i just went back and all of my post had been deleted but the last one. i answered a question and no replies since

on their actual tech forum you linked yes.
also on facebook didnt get to much help at all. everyone wants my global folder and im not to keen on giving that magical stuff out.

Trust me, there’s nothing secret in there... lol, but I bet they’ll figure out the problem. A lot of smart guys on there and Danny Cabral is good at troubleshooting. If you wanna keep it secret, hire someone to remote in and figure it out.

i have to no avail. sent logs, etc.. all danny does is change my posts to where i dont understand it. complains about my writing as if its in text form or some ****. im about to post in russian. so he can translate it and complain about that to and delete my posts all over again.
im pretty sure i have a bad ecu or harness. as thats the most common issue g3 hemi guys have had with same issue im having. i just dont have the money or desire to spend money on **** that was new but never worth a damn from the box. holley ecu isnt cheap neither is the harness.
Totally different vehicle, but installed a Motec on a late model foreign job and had issues with it bucking, tach pegging to 15,000+ RPM, and other issues. I worked with their East Coast guru for awhile, sent in the Tune for him to evaluate, etc. The West Coast Expert was then brought into the discussion. In the end it came back off. They charged a 20% restocking fee for the ECU and the harness was ours because I modified it (of course?!?).
Later I realized the issue was that the Cam Position Sensor was mounted on the cam that advances/retards. The Motec was just used as a fuel & ignition controller, with all the other controls (tranny, gauges, even adjustable cam timing) left to the factory ECU. The cam would change relationship with the crank sensor and BLAM! This eventually burned up the cats. Oh, and you think your Holley was expensive, price a Motec!!
