cannot for the life of me figure out how to rescale for larger injectors on this jeep pcm.. its a 02 jeep wrangler 4.0 supercharged with 42lb injectors and having all kinds of problems tunning it
I?m definitely going to put them 46lbs back in and try them again I got the tune pretty close but I was about maxing put the stock injectors under wot.
Alright I added a good bit of fuel and it does ok now idle and part throttle but anything in boost goes to 19+afr but thank you I will try the new tune..you do know I have the stock injectors right?...
No it goes strait to 19+ on first start up iv fixed it though were it?ll idle I?m going to work on the fuel tables tomorrow
I added alittle fuel to the entire table,now I?m going to see what that does
Very lean
Ok thank you doing it right now
Alright thank you spoolboy will do that
This is by far the most aggravating pcm iv had to mess with iv tuned many all motor and boosted LS?s and a few coyotes but this by far beets them all..your just very limited to what you can do with...

Once I get my tune done I?ll post it in the tune repository
Iv got the scale multiplyer set to about 190 right now and it?s working out very good I could still got alittle higher in only running about 8-9psi
No closed loop until I get my shit half way right
The problem with dividing in half is I ended up going from 20kpa idle to 40kpa wot so not enough roof for adjustments so I?m playing with the map scale still to try to get my fuel map as large as I...
Kinda but I?m still having problems getting fuel under boost I?m leaning out
its still screwed up its fine until it hits any boost then leans out iv got stoker007 helping solve the issue

Alright give me one sec and I?ll upload it
It worked divide the map scale in half went from 244 to 144 and worked perfectly know im idling at 20kpa instead of 70kpa like I was before
I got it figured out loaded the stock tune back up and changed my map scale in half from 244 to 122.
I?m going to start completely over with the tune this was me messing around with everything trying to work around the map sensor not being right
After I get this map scale figured out I?m gonna turn it up for sure I got a air to water on this so it should be fun
Iv been going through hell trying to set up my srt4 map sensor..the newer model pcms are easyer to do
No not the stock tune I set the timing low to be safe while trying to get the fuel right
