car wont start after attempting to program ecu with hypertech

Thorazine_IM

so i attempted to program my 2013 370z ecu with hypertech. it started programming it but it never finished. and it keeps saying it couldnt read ecu. called hypertech and they said the unit is not made for 2013 and would only work for up to 2011s and that they havnt come out with a tuner for 2013s. now my engine is making this weird noise when ignition is put to "on" the noise sounds like a fan is on. or like when your laptop is loading a cd. something like that. and to make everything fun the car would not start. any input on this? im thinking hypertech messed up my computer? prolly needs to get reflashed by nissan??

Call them back and make them fix it! Does it say anywhere on the packaging not to use it on 2013?

I don't know about the packaging but when you use the "Find Products For Your Vehicle" search on the Hypertech site, 2013 Nissan 370Z is NOT listed.

Didn't you look it up to see if it worked first?
I know the COBB AccessPort only works for 09.

I hope you get it sorted out!

First mistake, not properly doing your research. You wouldn't have gone with hypertech to begin with much less using a tune that is not designed for your year of car.

Maybe resetting your ECU will fix it I just don't know. Once again research you will find how to do it located in the forums here. Can't hurt at this point.

My guess would be that the ECU is toast. Hope a reset clears things up, because a new ECU isn't going to be cheap.

The ECU is stuck in flash mode. Ask if hypertech can repair ECU's that are stuck in flash mode. If there is no way to recover, you will unfortunately have to simply replace the ECU. We have had similar issues with the older Cobb accessports on the 350z's. Luckily Cobb tuning has been able to recover the ECU's that we have had failures with, but since they never supported the 370z platform they wont be able to help.

Good luck with your issue!

Glad you chimed in! I hope others learn from this.

Hey Alex, Cobb DID make an AccessPort for the 370Z, ONLY for the 2009.
Cobb/UpRev still might be able to help because they both still work on 370's in TX

Doubt it. The ecu is basically a blank disc right now. Just like back in the old days with floppy disks. If it had an error while loading the floppy, basically the whole disc was corrupt and you just trashed it. I hope this isn't the case for the OP but

You can potentially recover the ECU if you can get it out of flash mode. I would contact UpRev or Cobb regarding their repair services.

I am not familiar with that specific software, but it seems to me that with something as important as flashing your ecu, a backup would be made prior to flashing... They might have that built into the software. Either way you need to contact the company and see if anything can be done. It is their product, they would probably know best what if any the solution would be

so nissan has my car right now. i didnt tell them i was messing with the ecu hoping to get the repair covered by warranty. i just said car wouldnt start over night. unfortunately i have an aftermarket alarm installed. and of course they said the people who installed the alarm installed something that fried the ecu just so they avoid paying under warranty. is there a chance that the ecu is not fried? maybe theyre just saying that? theyre trying to charge me too damn much. we all know its not the alarm. one of my sources said the remote start interrupted the programming which caused it to not finish because the remote start is drawing power from the battery. im trying to send uprev an email but it wont go through. i guess ill call them on monday. i need to get my baby back on the road!

Yeahhhh... Remote start isn't the best idea, I've come to find that almost 100% of them fry the ECU over time

Normally i would say get it in writing from nissan that the alarm system fried ecu. Go after the alarm company and make them pay damages... But honestly, since you used a product not designed for your year car and ruined it yourself, i would just feel wrong doing it. But to each his own, just trying to give you ideas how to get this payed for
