Need help with base map: Osiris, built engine, vortech, DW 800cc
Ok, I'm having GRD tune my car next weekend. I'm having issues with this osiris tuner. I had it setup and working fine with my 440's but i just switched to a CJ motorsports RFS and DW 800cc injectors.
Full built engine
ported heads
tomei cams
vortech 2.87
dw 800cc
cj RFS
headers, test pipes, TD borla
HPX PMAS maf
So, earlier my car was idling like crap and i adjusted the k value down a lot. It started and idled better but i couldn't even get it out of the driveway. As soon as i put load on the engine afr would max out and stall the car.
I kept messing with it and found a happy medium. Car starts hard and idles kind of crappy but i can get it to bounce around 14.7 when cruising. My fuel comp charge has some huge numbers on it though. Like in the 130's.
I can't find the proper injector latency for the dw 800 injectors and i know that will cause a huge problem.
I need to get this cleaned up just a little more so i can have piece of mind to drive this car to chicago (from stl) to get it tuned next weekend. Any help would be appreciated: dw 800cc injector latency, possible starting point for k value, etc.
I can send my recent cipher and logworks logs along with my osiris map for those that can help.

yep, i just received that email from mike this morning.
I'm running the PMAS.
I got the car running and back to St louis but i need to drive it to chicago this friday. I'd like to have it running better before i make that trip. I'll put these in tonight and see if that changes anything. Chances are it won't make too much difference though.

Vince informed me that the mapping for the PMAS alters the K multiplier so it won't be modified the way suggested at other places (cutting muliplier in half when doubling injectors).
That clears up a lot of confusion as to why my k number was so high with my large injectors.
