tuning with ceddy mod.

[bjmauck]

I've gone from 550cc and a 16g to 1000cc and 50 trim. I've set the injector size to 1000 and messed with the latency and it idles good and afr is around 15 and when I'm trying to set the wot it will sputter bad and afr is at 16. I've tried to adjust the latency and it doesn't seem to change much. Any suggestions?

Fuel injector deadtimes affect very little outside of Idle...

I also highly doubt your "1000cc" injectors flow that much try something along the lines of 940 for starters

I came down on that some so I guess I'll have to come down some more. It's been a while since I tuned it for the 16g so I'm kinda rusty on tuning.

Ok so if I'm lean on wot I need to go down on injector size correct? Also my car is never close on the injector size. I had my 550cc down to 350cc before it would not lean out. Would that be a maf issue? I have blt already.

A log would be your best best for any sound advice, I don't tend to give out advice with out some sort of one as it's impossible to diagnose cars issues off peoples rather vague descriptions of problems.

Regardless with out something to go off of whether it be a log a or a lot more info then "you think it could be X" It could be a number of things. I have no Idea how your ROM is setup or any potential problems with your setup... Could be anything from that to you not holding fuel pressure to some of settings in your ROM.
