I bought my G and the spec sheet indicates that I have split second timing in regards to my engine control software. Is this the same as a revup? I saw a tuner last week and he suggested I go with the uprev osiris software. How do I know that this is not the same thing?

 

What year is your car and is it auto or manual??

 

it's an 06 6MT

 

Split second is just engine control software. Revup is a model of VQ35 engine. The revup is in all 6MT 2005-2007 G35 Coupes. You have a rev-up and you are using the stock JWT engine software. If you are making good power and don't need anymore/anything else with your car, just stick with the split second box. It is reliable and generally has your car more on the safeside. I ran it for 4 years on my stock block with 0 motor issues.

It seems like you should have done a lot more research before you bought your car or modified it the way you have.

 

^ exactly.

 

It's simple math. What costs more. Buying a G bone stock and adding all the components or buying one with everything on it and learning as you go? I bought this car with turbos and a built motor and have had only minor issues along the way. Minor being simple oil changes and new steel braided turbo lines.
@Canadian: BTW my car was built by the same guys who built yours.
