Im finally getting hold of a datalogit and I can finally update the software for the 1600cc injectors that are in there. It currently thinks I have 1200cc, my primaries are 850cc. Ineed to know what the lag time adjustment, overlap should be. Any help would be appreciated.

 

I'm working on the same thing with my big injectors. I beleive all of them are actually 1680cc. You might want to look into that. I set the size to 1680 and the lag to .40 as that's what I had read from Jason at the RX-7 store. I can't get a hold of bosch to get the actual lag times for my injectors so I'm going by what I read. But I read a lot of different things. I set the Sec Transition to .996. I'm not sure what it exactly does, but when I adjusted it above the 1.500 stock setting, my stumble got worse. I set the injector overlap set 9,8,6 top to bottom. Those numbers are a little higher than I've seen others, but I stumbled untill I changed them to that. I've still got an occasional stumble if I hit just the right conditions, but it's much less noticeable. Just to cover my butt, I have no idea if these will work for other vehicles. There are others with these settings out there who probably know a bit more than me. I am not responsible for your engine if it blows itself up.
