Help, car can't start after supercharger reinstall

[ScionOfHorus]

Car turns over, then dies immediately. Video is on the Facebook page, and can't upload it on here. YouTube being a pita, not there either.

Help? After finishing installing my supercharger and flashing ecu this happens. Even when i tried to go back to stock tune it happened.

Originally just getting error code b14a1, error code can't be cleared by Ecutek.

When I click "check ECU connection" I get "unable to communicate with ECU" but everything seems to work just fine... Idk.

Tried 3 different versions of tunes that were working last time the supercharger was in, tried ecutek's stock tune, tried reinstalling the Ecutek software on my computer.

EDIT: Videos:

if you have changed map sensor car wont run with stock tune unless you put in stock map sensor and vice versa.

your map sensor for SC may be stuffed , onmi sensr aparantly fail occasionally

that error code your getting is related to a\c climate control light sensor nothing to worry about.

if you cannot talk to ecu via ecutek thats a bad sign , hopefully it just a bad cable connection and not a corrupted ecu flash, it also might be ecutek licienceing issue.

if the car starts and dies thats a good sign

see if an obd scanner or similar can talk to ecu, if so then it likely ecutek licience issue talk to ecutek guys about renewing licience.

Stock MAF and MAP sensors. Both have run this supercharger before with no issues.

Doesn't it throw a code of somekind though?

Yeah, I'm not sure what's going on with that, since everything seems to work except the check ECU thing. Because it goes through the flash process completely normally.

Hmm, not sure if it qualifies as starting and dying, I'll upload a video later of what's happening.

They seem to do just as much as the Ecutek cable does. Used both an OBD Link LX bluetooth adapter and a mechanics OBD2 scanner. At least I think the so, neither picked up the a/c code. The BT device was showing engine data, so I know it was working.

It sounds like it fires briefly,which means that the ECU itself is working. Otherwise you'd be getting no fuel so it wouldn't get past the starter motor. Out of interest, which SC have you fitted? Have you re-fitted the same SC and with the eact same tune? I'd guess that something isn't connected correctly, lack of ground perhaps?

[ScionOfHorus]

Same SC, tried both an old working tune and a newer one that I had never used before I took it out last time. Also tried using the stock tune from ECUTEK

[wbradley]

MAF plugged in? Did you leave a rag in the inlet pipe accidentally? MAP plugged in? All vacuum hoses conne ted? Solenoid pipe below throttle body disconne ted. Lastly, tune file corrupted?

[ScionOfHorus]

Yes, no, yes, yes, pipe connected, time file shouldn't be corrupted, unless ~7 downloads all corrupted in the same way.

Try flashing to stock just to see if engine starts (don't rev it).

Tried 3x times already, even completely reDL'd the ecutek software three times to be sure there was no files corrupted. Used 2 different computers, and 2 different networks. Same issue.

If the car cranks its highly unlikely to be corrupted tune of bad flash.

If flash corrupted/bad it wont even crank

It likely hardware issue.

That seems to be what I've been hearing. Been told might be bad MAF or MAP, a ground somewhere fucked up, out something disconnected that I couldn't find last night. Heading back to where I left my car to do more looking soon.

Found the problem, it's the MAF extension cable. Car started when I moved the MAF close enough to not need the extension cable.

Excellent! MAF was my first thought. Glad it got resolved.
