So I'm trying to get my AFR during spool up to be in the mid 12s. I spend the last hour to try to occomplish this and no luck. I mean I'm not even close. My map use to be nice and smooth and now it is just starting to look weird. Can some of you guys post up your fuel maps where spool is around12.5 A/f?

Thanks

here you go

edit: to add its not perfect... once i hit full boost 290 in 3500rpm cell it dips rich 10.8 afr.. i never corrected it because i feel so much more torque that way.

hediki12

is your lean spool disabled?

Thanks for the map. LS in enabled. My spool area (2.5k-3.5k 100 load through 300) is starting to be even richer then any other part of my map.

Any one else has maps with LS enabled?

hediki12... why so rich from 4k-8k in the 10-30% load?

hediki12

My inner rice boy. Haha. Its for flame inbetween shifts timing is also retarded in the same zones.

But turn lean spool off it will give you better consistancy, appauld tunes with l.s on but even he admits its a headsache and a longer process.once you do that you'll see that getting your 15.5-12 afr is easier.

lol, do you notice any faster spool between shifts with it as well?

hediki12

to be honest ive never changed gears fast enough for it 2 pop/flame . but when down shifting and heal toe-ing i love it. i havent beated on my car yet to find out tho. ill do some logs once im done retuning the map and scaling my injectors again, haha.

its taking you till 3500 to hit full boost in a evo3 16g? you might want to lean out spoolup to atleast 12.5-12.8.. a evo3 16g should be fully spooled by 3000rpm.

At what point should an evo 8, stock turbo, 272 cams be full spooled?

Also, in that fuel map, i noticed that that all the low RPM high Load cells are leaned out as well, or in the 12 range tapering to 11's. I ask this for the stock maps have these set richer then spool area. Here it looks to be similiar to the spool area. Does this help spool?

Ghost...you should be at full boost by 3300-3500 pretty easily, if not even a little sooner. See my thread about tuning for faster spool. There is a lot of factors that help, timing and fuel surely do.

Cliff notes....a little less timing and a little more fuel seem to help bring on spool faster. As will other certain mods. You want a ton of pressure before the turbo and as minimal as possible after. But you want as much heat as possible after the turbo to keep exhaust velocity up thus reducing after turbo pressure, kind of. You want whatever boost control method you use to hold as tight as possible up until peak boost.

What I found that helps spool the most and Tscompusa can verify this....add fuel at just before you start to come on boost (90 load) and make is spool at mid 12s afr. The onset of more fuel makes for much improved spool.

As for the OP.....+1 on turning off Lean Spool. As a beginner tuner having LS off will make your tuning much easier since you will get much better consistency from pull to pull.

Appauldd, is disabling LS as simple as setting the stop RPM to the same value as Start?

That is the old way to do it. A better way is to set Periphery FBA bit 0 to = 0
