I have been reading about the accel enrichment table to fix this but no matter what I do it still dips into the 10's for AFR right when I mash it after shifts. Also, if I just floor it in any gear it holds a great AFR to redline, but when I start going through the gears it slowly gets richer and richer in every gear, which causes the AFR to dip down even farther at shifts. Would any changes in lean spool fix this? Should I just disable it? Can I do that without getting rid of my current tune?

Thanks for the help everyone, I have been searching ALOT.

Also, this is on a 06 MR

 

Richer and richer in every gear when rowing through the gears is from Lean Spool being on.

 

Thanks for clearing that up!

Can I disable it without getting messing up the tune?

EDIT: nvm on the last part I just read everything I need to know I think, Any ideas on the accel enrichment? Also, I have read about some interest on this but havent found anyone that has actually done this, I dont want to retune my entire fuel map after I had it tuned. So can I just have lean spool stop at say 4K and then tune 4k and up?

 

mine does the same thing, well i tuned it for 3rd gear 11.1 by redline....but in 4th its like 10's across the board....i'm also looking into the lean spool disable

 

Anymore ideas on getting it to lean out after each shift?

 

Disable Lean Spool like Razorlab said. Follow THESE directions.

 

Lean spool will help onset overrichening. In fact, you can directly input and control the amount and ramp within lean spool using the 1D antilag map (1st four cells on incorrectly labled throttle collumn) which makes it easyier because it doesnt seem to be load based.

It's the X-Tau setting in ecu. Used to avoid surface wetting or excessive leaning with rate of air volume change (e.g., rpm, gears, load). When car has more HP than stock it knocks it off balance. I think it's really your AFR is not getting richer while going through the gears, but that it's leaner in lower gears. But eventually it can get tuned out.

Not sure what maps are involved but it's not entirely accel enrichmnet. MAF smoothing and scaling probably play too. I eventually got rid of the problem but I forgot which combination of tweaks did it, but my accel enrich is still stock.
