Thread: Why is there still KR?

It looks a little too rich with a big IC. Too much fuel can also cause KR.

I'd first check TM setting for third, it's common for it to kick in when you are in third-fourth, but that there can still be tuned out fairly easy if you know where to look.

Just my opinion though.

if all of the fueling is stock then that injector table needs to be fixed for the addition of the larger injectors...if you didnt already.

also may have to do a tps re-learn on that northstar if you didnt already...i see it was reading 99.60 % at what i am assuming is suppose to be wot?...may want to test it out while scanning with the key in the run position and look at idle tps% and wot tps%



one persons was reading 50% tps at wot with his aftermarket tb setup....did the relaern and it fixed it...


or it may have something to do with scan depot because i am lacking the fimiliatary with that program



also raise those shift points to around 5900 (compleated shift) as the sweet spot in the power band will most likely be in that area with the 1.9's...the sweet spot being after the shift is compleat and the rpm's drop back down

I didn't even catch that....
definitely need to skew back the injectors if that hasn't been done.

and...lol...fwiw im running 910-920's for o2's and i have basicly the same setup.still not done tuning though


Thanks brian! lol

What do you mean? what u said didnt make sense to me...and yes reptiles name is brian lol

Well not being fimiliar with dhp that sounds like the table that you need to modify to get rid of any torque management...witch causes the kr during shifts so maybe not as off topic as you thought.


maybe this will help you...If i remember correctly in hpt the tables for tm are...maximum torque> rpm vs. gear, vs gear, vs. rpm and spark retard > vs. torque reduction ( this table is the table you will zero out...what this does is disable any spark related tm all the other tables that i mentioned you will want to increase the value to...thus increasing the amount of torque Before the pcm retards any spark


go ahead and post all the tm tables you have available and i will try to figure it out...but that sounds like it..



can u take screen shots? if so post a cupple of those up


the tm tables excluding should be triple digit numbers that increase with rpm or in some cases gear. stock shold be around 258-384 and for the spark related timing it should only be double digit numbers ranging from 0-50


you should have 4 tables for tm and then another 3 tables for tm under the tcs tab...yes? or no?

The table for 42lb injectors and the maf table for the new throttle body is in the tune on the car, it is not running uber rich from a stock tune on new bigger injectors like you were thinking.
