Uprev in S'pore.
 

Last night try to get my E.C.U. an Uprev re-flash,agent told me,there are no maps for my E.C.U.,so he download my standard map in my E.C.U.,then he mail it over to Uprev,rewrite it & send it back to S'pore,hopefully in 2 weeks time,have anyone encounter this before.?

I wonder is the E.C.U. of U.S. cars same as the one in S'pore.?Why my agent cannot find a map on his system.?

Yes. On my 2011 Nismo I had to do a ECU Dump for Uprev. They have to patch the Rom.

Yeah, I had to do the same with my HK ver. 370z.
370z selling in different country may have different version of ECU.

Have you get your reflash map back.?

Uprev requested my stock ECU dump so that they could work on the base files (e.g. Maps). They will send back the base files and you are ready for tuning.

Uprev maps installed,not much power gain,before tuned,car runs 'rich'[10.5:1],lean out the mixture now running 12.5:1,car now a 'bit' smoother....power same.

may i know what mod you have at the moment...

would like to know also if i could tune the car by myself without a tuner?

any advice

Your car must be on a Dyno,now my car have HKS Hi Power exhausts & K&N drop in Air filter.
