As far as the gauge moving give or take a point, that could be more to do with the wb feedback rate than the tune. I'd be happy if I got my car back with 2% trim and a steady wb readout.

Have a listen to the power and speed podcast EP with Greg Banish. Lots of good info about cats and lambda. Link to comment Share on other sites More sharing options...

Ralph Wiggum is right about the sh*tty idle. With a good tune a car should idle smoothly at a wide range of afrs. Link to comment Share on other sites More sharing options...

Lots of good info about cats and lambda. is Ralph a tuner him self just curious seems as if the guy knows his stuff and ya should idle fine from 11:1 to close 17:1 which it does, easy way I find is to block of the FPR vacuum so it raise's pressure saves jumping to tablet to edit tune whilst on the subject to form a VE table, is it true its slightly easier with a boosted application have only done a few cars in past still the same concept obviously but was a bit fiddly also in vcm suite is there a way we can go by pulse width instead of target a/f ratio if that is possible would make it 100 x easier for me Edited 11/09/17 01:13 PM by Boosting_G6E Link to comment Share on other sites More sharing options...

Am Not, I'm either A Street Tuner A Dyno Tuner A Racetrack Tuner But never a backyard tuner as although I've got a decent size back yard, getting up to speed and stopping without hitting the fence is very difficult.

They have the maps available for the returnless setups to scale slope based on delta P across the reg, just wondering if they are ever set up to use it as compensation on a return flow system as well. Regarding target pulse width no that is not possible, these ECUs are designed to meet strict emissions and hence use a complicated speed density model to achieve this. Targetting pulse width would mean you have no scaling for temperature/humidity etc, unless of course you meant base pulse width (which is then added to). You could calculate this in excel though I'm not sure of the utility as the target pulse width is always going to be scaled and hence not what you log.

But only because I've got a fuel lab pump and reg setup that varies pump speed based on return flow... The only return flow systems I've seen with FPS's are the diesel setups. Enable returnless control. We can all run mustang dual intank modules and pump controllers and get on with life. Link to comment Share on other sites More sharing options...
