Pro tuner for consult?

Sh0velMan

Any pro tuners with a lot of Uprev-specific experience willing to let me bounce some info off of them? I'm trying to figure out some weirdness I'm seeing.

Thank you in advance!

Going for a tune tomorrow, the promble is this i went once before but the tuner couldnt upload the tune in to my ECU, now he's telling me that he can upload some other 370z's map is that possible or even a good idea.

Megan370z

he probably couldn't flash your ECU because you have a 2013 with a rom that UPREV might not have yet.

All it need for an unknown ECU is to have the Dump ECU function on the Tuner/Pro Cable and Download the ROM from the ECU and sending it to Uprev.
Usually take up to 2 weeks before receiving the Uprev version of it to be flashed into the new ECU.

as far as your Tuner that want to upload another 370z map.... if the mods are similar the difference wont be that big but IMO, I would ask for a proper tune made for YOUR car.

Hey Megan370z

Had someone else telling me that the 274 was too high !!??

Maduro

Also what is the down side of putting someone else ROM on your car

Megan370z

the guy here on the forum said that 274wTQ was too high , he probably meant that the dyno read high because 274wtq is more than what we usually see from a fully modded VHR engine.

I did mentioned that you were pretty much spot on with your mod at 299whp. but I can see the 274 being a little bit high than average. its also depend on your setup. so don't feel bad.

as an example here on my dyno sheet , the only way I could be at over 275wtq was using a lower gear on a dynapack.
I proved this dynapack to be within 1% read(higher) from a dynojet a couple hours prior during that day.

in average the guys get like 265wtq *peak*
it will be different when someone is using a different intake manifold like the M370 since it shift the TQ down by like 300-400rpm which gives a small Tq gain in mid-range. due to longer intake runners.

Edit;
Also keep in mind about the SAE Vs STD dyno reading . STD being higher.

this dynosheet is in SAE.




Well, I'm not an official Pro Tuner, but I tuned a few different cars and I never tried this. Nissan made an update and it finish with an higher letter.
as example on my VHR ECU they made 1 update.
1EA4B / 1EA4A
they have several different Rom per year and some has update.
As long as you stay within what your ECU accept . there will be no problem.

All I know is I think you cant flash a rom with a complete different serial.
depending on the serial you have. I remember at one point where my VHR was the primary and I wanted to flash my HR Ecu . it just didn't work. Wrong system file, something like this.

Let me start by saying thank you,....... Just so I understand a tuner Can Not Flash a random ROM from some other 370z on to some one else's ECU because of serial numbers??

Baer383

correct!!!!

This is why I ask if a ROM from a different car can be used on another car :

"I can't post the ROM file because of size limits. Shoot me your email if you want my current ROM file"

This is a question someone asked !!??

Baer383

I don't know why you just email Uprev they will give you a back to stock file and a Uprev stock file and your good to go it is free and takes about 3days.
