Since the injector scaling is not available for the utec yet, does anyone have a good starting point to use w/ 700cc injectors? Just trying to make sure that we're not way off to begin w/.
Thanks,
Jeremy

 

Your just going to have to pull fuel everyware. You should post up in Nasioc this question. They have been tuning utecs with larger then stock injectors for a few years now.

 

Thanks, I've posted over there. If anyone else has any suggestions, feel free.....

check with buschar or dynoflash. They can help with the setup.

 

hey , i just started tuning with 750's, its a ***** from scratch but im a nice guy,
im using a gt35r, so the spool up may be a bit different,
but at the bottom lean rouphly 13, in the middle about 22 and at the top 32,
and fill in the gaps to start a rouph map, you may want to lean a bit less than this to start with , with these numbers im at about 11.4 afr, im tuning at 1.5 bar..and youll need to bump up timing at the bottom and in the midrange or youll have no throttle response
only problem im having is the afr is dipping back into the 9's between shifts so its pops betweeb shifts. let me know if yours does the same thing

call ken @pruven performance by far the best or one of the best u-tec tuners there are.

 

thanks dude. i'll post some results in the a.m.

 

Yeah, I was going to say I calculated about a 25% difference so your scaling should reflect removing approximately -23% fuel flat across the board in the entire map.. Thats a good starting point, though depending on your mods there's going to be some rich spots, and some lean spots just like stock.. then you can do some real tuning..

you can start with my map and select everything and do a -23% for everything including the 0% column.. that should scale you close to the larger injectors..
