Just finished up with a customers Greddy TT Kit and engine rebuild and after getting it running (running bad and way to rich) he decides to upgrade to the ultimate. What's the best path to upgrade this so I can try to come up with a price quote. Can I just add the new wires required to the old harness or are the harnesses completely different. I see that Greddy sells the harness and has the rpm converter built in but I really don't want to cut out all the soldiered wires already there if I don't need to. Thoughts? Also how good is the ultimates "ability" to self tune to a desired AFR. Would be nice if I can get it close the the right ratio before taking it to a dyno.

 

I would suggest your customer a different engine management, he's probably going to run into problems with the emanage, if not now later on down the road for sure, suggesting a Turbo XS Utec or something, but if emanage is the road then i dont know i think you have to buy the whole new console for ultimate, correct me if im wrong

 

Yeah I did suggest that. Came here about a month or so ago and learned the blue was junk and got about an even mix of cheap alternatives being EU and UTEC. I liked the idea of the UTEC better but he seems to like the EU. I'll do either one but I was hoping the choice would have been made before putting on the blue. At least then he could have sold it as a new in the box (well without the box) unit. Greddy seems to be taking their sweet A$$ time getting back to me on this one.
