Did you pressure test the primary rail for leaks after installing the 850CC in there ? its also advisable to get another new set of spark plugs an try again, in some rear cases i have actually got bad plug or plugs which doesnt fire at all new out of the box. you can try with less fuel and increase until it sounds like its gonna start up to avoid fouling the new ones. you can also use the ignition test function to test the coils and spark plugs.

if you can post a pic of your E-shaft(crank)angle sensor complete with the entire trigger wheel, would be able to better advise and would be able to give correct instruction on how to calibrating that particular trigger

From my understanding shouldnt his trailing map have all negative values, -12 isnt bad from my experience, until he can get to a dyno. I think i got this one

a bit confused pls give more information on the setup and your goal/s or intension/s

thanks for the reply, its a boosted FD engine and yes i totally get what you're saying and yes that particular engine porting was pushed as much mechanically possible. Was hoping there is something i may not be aware of which would have helped smoothen things out a bit , just my luck :D

unfortunately i dont have any logs but i will post one as soon as i have access to the car again, its has a 90mm RW throttle, and a xessesive LIM. i may have another which may have same or similar issues, sorry for the late reply, hope to get back to you soon with that log btw its g4 unit and yes im using map as load, do you think its advisable to use bap/map xover ?

Hey guys I was wondering if there is anything I can do to address the jerkyness of a bridge Port 13b at the lower RPM and load range for better drivability especially in the cruising around zones
