Has anyone used uprev to self tune their car? I've tuned a few of my old turbo cars and figured I could do this car as well but I am curious if the program is user friendly. Any input would be appreciated.

 

I self tuned my car with UpRev. It's NOT user-friendly. The values are not standard values for the tables. Like for example (and this is off the top of my head) - On one of the tables, you should have MAF on one axis, and RPM on another axis, and you change the values of fuel flow in the cells. Well, instead of MAF, it would say "Data Word" as the units that you are changing. Another example, for timing, it's not degrees (before top dead center), no in UpRev, it's "Burn Time". So the same number in the cells would have a different 'Burn Time' depending on the RPM. So a '30' in the cells in the 3000 rpm range is a very different timing value than a '30' in the 7000 range, based on how fast the piston moves at the different engine speeds. It basically looks like the software was written by computer hackers who got into the ECU, but weren't familiar with automotive tuning standards. Ultimately, if you have patience, you can tune it by increasing or decreasing values based on logs. In that respect, it's the same as tuning anything else. But no, it's not something you can just open up and know what to do with by just looking at the different tables you have available.

 

I started self tuning my car back in November or so and agree with everything RadioFlyer said. Unlike you though I didn't have any prior knowledge of tuning so I had to learn things from scratch. From my understanding the burn times are how nissan ECUs work and that's how things are represented in Uprev.

They have just recently released a simplified timing table with their ARC features for G37/370z which is supposed to go more along the lines of the automotive tuning standards mentioned. Since I have a VQ35HR I haven't had a chance to try that yet.

I would think if you've tuned before it shouldn't be as difficult to learn than if you never have tuned a car before. One key aspect is to make sure you focus on dialing the MAF sensors in, that is where the bulk of my time has been spent.

 

Going to bring this thread back from the dead here...

Sold the old g37 and just recently purchased a q60s with the 3.7L still at the heart. Looking back into self tuning with uprev.

Do you scale the maf tables using long term fuel compensation tables? Also, has anyone accessed the new arc features? I don't mind a little learning here but not wanting to learn the reinvent the wheel. Hoping with all the new updates the user interface has improved.

 

 

I assumed with ecutek you had to be a pro tuner to actually utilize the program in it's entirety.
