Uprev Tune on Nismo?
 

Has anyone done an Uprev Tune on their Nismo yet?

no thinking about it..... just cant justify that $$$ for a n/a motor like ours

Yea. I currently have Mine done. I had to do a ROM Dump for Uprev on my 2011 ECU ( 1A32C ). Uprev and I have not really started tuning it yet. Basically all we have done so far is the patch ROM and smoothed out the the Fuel table.
I don't have an dyno's yet, but maybe in two weeks or sooner. I will try to do a stock Vs smoothed out the the Fuel table.

Nice! im interested in seeing the comparison

Ditto.

Thought I would share some map shots of what we have done so far. Nothing to big just a comparison of OEM to Smoothed out. It's nothing to drastic. All that's been done is just the fuel.

Map One is the one we have worked on. Map Two is OEM

In for more post

Here you go. No to bad for stock. Between the two maps there was not to much deference. Maybe 2 hp/tq. So here is my baseline. The Car seems to like fuel.

Wait -- is that before or after tune (you said baseline, which implies before)?

Also, can you get SAE corrected numbers (STD tends to overcompensate for NA cars)?

Finally, if you can get the drf files from the shop would you mind emailing them to me for my database? jlitman@mail.usf.edu :tiphat:

What is a ROM dump and why does it have do be done? Is that on the Nismo models only?

My Nismo base lined at 298hp as well on the Dynojet at Z1 Motorsports

A ROM dump is where you make a copy of the ECU programing. You send it to Uprev for patching. Once patch it gives you access to map switching and Real time tuning. You only have to do a rom dump if there is not patch Rom. I my case I have a 2011. There was no patch rom yet.

This the OEM Tune (Stock). Like I said there was maybe 2hp/tq difference between map one (Smoothed Fuel) and map 2 (Stock). All that has been on on may one was a bit of fuel taken out.


Attached.

Would you mind emailing them to me? The zipped files are corrupted -- I don't think you can zip drf's without corrupting them... thanks!

Works fine. Sound like you have other issue causing that.
