enthalpy ecu question

[lazysk8er2]

so i just put my enthalpy ecu in and for some odd reason 2 things occur which are probably basic answers so lemme know

1) it locks my key iin the ignition. it wont let me push the button in. the odd thing is tho the stock sr ecu doesnt give me a problem. only the enthalpy ecu wont let me take the key out. car used to be auto btw.

2) it idles fine and boosts great but when i let off the throttle it dies. ex. if i rev it up in neutral and let go of the pedal the car dies out. the stock ecu never had a problem.

the tune is for what my upgrades are so thats not a problem. i dont have any shorts or w.e. im pretty sure i dont have any leeks cuz it wouldve shown with the stock ecu. my z32 maf is fine cuz i installed it on my friends 300zx and it worked fine.


3) new symptom. car wont turn off even after i turn the key in the off position. again this only happens with this enthalpy ecu and not the stock one.

More info on motor, KA or SR? What kind of ecu is the stock one, and what kind of ecu is the Enthlapy.

The stalling issue might be maf turbulence, or being a little lean at idle will cause the motor to stall too (mine had this issue).

red top sr with a #62 ecu for both ecu's

Is your car an s14? This really shouldnt be possible because it's not an electronically driven lock, it's purely mechanical from my recolection man..

Make sure your Blow Off Valve is not leaking too much. Made sure your Idle Air Control valve is "screwed" open enough, open that bitch up

what?

Sounds like power is wired wrong on your wiring or plug for the ECU. Did you send your stock core to enthalpy? or did he send you a new one






The last one sounds more like your Turbo Timer is smoking crack.

Shitty turbo timers will do that, it doesnt really sound like your ECU...I could be wrong.

If you dont have a turbo timer to begin with then your wiring is haxor

:ssex:

yea no turbo timer on this car installed yet. i sent the ecu back on thursday well see what happens.

[lazysk8er2]

it was indeed a shorted circuit on the ecu and enthalpy fixed it. should recieve it soon.

[joe3180]

key stuck....dont know how that can happen....i have the same ecu and i should have it up and running in the next week or 2 and ill post if anything like that happens to me. but hope that is fixed for you now.

[lazysk8er2]

just to verify my key comes out fine and it was an ecu related problem. something shorted internally and needed to be looked at and repaired.

thank you enthalpy!
