I'm just about to be finished building my DE engine, and I know the factory ecu won't be optimal, or even run the engine at this level.

I know that Uprev will allow data logging, but it would still need to be sent somewhere for the tune where as the TS is the whole updated ECU.

This car isn't going to be anything that will see the strip, just a daily driver with around 300whp.

There is a guy on CL who has the TS computer for my car, and wants $400 for it which is in the range of the Uprev.

Here is the TS website for those who are unfamiliar, and yes my car is an Altima.......

Just get Uprev

 

I don't know much about TechnoSauare, didn't even know they were still around. UpRev is good, been running it on my car forever. What part of Alabama are you in? There should be some tuners around there somewhere.

 

If you're up for the drive, go to Z1 or TopSpeed. Otherwise, UpRev and Motion Lab Tuning both provide e-Tunes (which will require you to purchase the cable and data log certain runs).

I'd stick with UpRev and drive over to get a pro tune.
