car wont start after attempting to program ecu with hypertech
 

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 :ugh2:

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

Why not just tell them the truth so they can better diagnose the problem? They might just need to reflash the ECU or something, without having to replace it with a new one and costing you alot of cash.

You screwed up. Take responsibility for it and quit trying to make others pay for your mistake.

how do you know this?? should i just have them disconnect the remote start after the repair is done?

So screwed...

Wellllll... My friend's Infiniti FX 45 burned one, my 2009 Maxima burned one, but the dealer replaced it because I was cool, my ex's Toyota Yaris burned one, and my friend's Honda Accord burned one...
My Maxima killed it in a year and the other cars were at various times, 2-4 years

Looks like catastrophic user error. Don't think hypertech had anything to do with it.


Phone Tapatalk *nix ...

even if i do they already told me ecu is fried. i asked if they could just reflash they said no they need a new ecu. its not like if i tell them what i did theyre gonna be like oh yeah? we were just kidding. ecu is not fried. we're just gonna reflash it. lol

Exactly what is the definition of "fried"?

It's possible that the diagnostic unit is seeing "scrambled" data and assuming that the unit is "fried". If the techs know that you scrambled the data, they may be able to reflash the unit. Maybe not.

Maybe the techs at your dealership are not very knowledgeable about ECMs and/or 370Zs. Maybe not. Try finding a dealership that may have more experience with ECMs. At this point, it's worth a try.

Maybe your ECM is fried beyond repair. Still not a good reason to so easily dismiss MJB's comment.

might as well just tell them since theyre blaming the viper aftermarket alarm and making me pay for everything anyways. but then again theyre gonna be like oh ok so this guy lied to us never believe him again. imma have to just go to a different dealership.

I found an ecu. Just inquire carefully if its compatible.

http://www.the370z.com/parts-sale-pr...g-6mt-new.html

I pmed the guy. Hopefully It's compatible. I have a 6MT 2013 base model 370 z with a CBE and some suspension mods. So in case it's compatible maybe I should just have my car towed back home and do a DIY ECU swap? I doubt they would install an ECU bought outside the dealership. How hard is the DIY ECU swap? Is it safe for me to do it? I dont want another accident.

"The ECU has a security code that is keyed to the car and the key, kind of an anti theft thing, and that has to be reset by a programmer on the new ECU before it can go in." --->found this in a nismo ECU swap thread. they were talking about swapping the base ecu with a nismo ecu to get more power. so maybe im not gonna be able to just buy an ecu removed from a different car and install it myself??

Oh, what a tangled web we weave ...

The module will need to be reprogrammed to recognize your fob(s) and possibly other sub-systems. IIRC, this has to be done by a Nissan dealer for security reasons.

I haven't seen it mentioned anywhere, but you might be able to get the fob that belongs to the used module and not have to reprogram. Just a guess.

Maybe talk to uprev? They have the ability to recover ECU data when someone flashes thier system incorrectly. You may have to purchase the software, but then at least you end up with another piece of equipment you can use.

It's bricked -- google "bricked ECU" for more info

I believe you might be able to get it to unlock pulling the battery cables and leaving it like that for a few hours to clear everything out of memory, but if that doesn't work you'll have to have it dealt with by Nissan.

There may be other tricks to un-brick it you can find with searching -- not 100% that my suggestion works alone, so do some research to confirm.

Hyper tech is at fault ONLY if they don't specify what model years it works for -- in other words "09+" is ambiguous whereas "09-11" is not.

How to Unbrick an ECU. Like A Boss! - Subaru Impreza WRX STI Forums: IWSTI.com

the subaru community has a diy for unbricking the ecu. nissan people need to step it up a lil bit and come up with one too! lol. i dont think im up for that much work though. its all good. i went the safe route and did everything through the dealer so everythings under warranty. they already ordered my ecu and is shipping from japan soon. dealer said its not available in the states. it makes sense though. how many 2013s out there fry their ecu? im probably the first one! it sucks not having my car around though. :shakes head:

If you need help recovering the ECU let me know .

-John

So what can you do for me, John? How are you gonna be able to recover it? Nissan said it's "fried" but who knows what that really means. They said they opened it up and saw some black spots indicating that its toast. hmmmm...

What the? That sounds like complete and utter BULL... And if it physically fried, I doubt the tuning thing would fry it like that... I could see it being bricked, but not physically damaged

Well sometimes people say they fried an ecu when bricked is the more appropriate term, to them not working = fried, But yea a reprogram shouldn't physically fry it.

I'm also curious, you said you have a remote start and a 6MT, how can you remote start a manual, do you leave a brick on the clutch when you park it? Or is it just that it has the ability on your alarms key fob?

:bowrofl::bowrofl::bowrofl:

There's a clutch bypass, that's why you shouldn't install one on a manual. Because if you leave it in gear... It's over...

(BTW, OP said the dealershit said his ECU was physically fried)
OP, go blame your remote start installers

During a program car a Ecu can be bricked or fried.. When we say fried we don't normally mean burnt it physically damaged. If your Ecu is physically damaged then you have a entirely different problem on your hands.

If the Ecu isn't I'm very confident that I can get the Ecu recovered

Let me know

How are you gonna do it?

A brick looks too sketchy. I just simply crazy glue the pedal to the ground.
But yeah there is a clutch bypass. And I always have to leave the car in neutral so it doesnt accidentally run over a cat napping.
