WTF, I just made a post and it got lost...ARGHGHGH I am already pissed enough, f-ing 5th grade math. What the hell are they trying to teach kids these days. Unreal!

10% on the maf justin? LOL Man, that will certainly make for a rich tune. How about just trying the B3643 table first. Raise that rate first before a bunch of changes. What is efilive's setting on that table? Like HPT is 0 to 4. (me 4).

Yeh Jim, when were at Hagerstown I couldn't tune, I screwed the tune up so bad and couldn't figure it out. SO when we were at MIR it was really the first time I was able to run that many times and tune. I was way into it. The funny part is, I wasn't able to get any faster times out of my adjustments, well, I got a 1/10th but after that, I kept getting kr. LOL Addicting when you have room to grow. What will we ever do when there is no more tuning needed? Mod again I guess.

 

No way Man, i am right on it!

It took me a minute to realize i could just open the .map file with notepad and copy and paste the info in there, but after that i was good. I got the MAP made and understand the settings to adjust. Now i need a little "ME" time to get all this stuff done....

 

I managed to get seven tenths knocked off over the course of 3 runs just from tuning. My first run was 15.0, i copied the high octane spark table to the low and ran again. That netted me a 14.7, i got no KR so i lowered my IAT spark reduction table by about 60% and ran again. I netted a 14.3 on that one with a 1.90 60' time and still no KR to speak of! If i would have eliminated it completely and bumped the timing a degree or two, i probably would have done even better, maybe 13.9x??... It got nice and cool that night which allowed me to almost zero out that IAT table. I am almost positive that that knock sensor needed time to adjust, i am seeing almost no KR at all now (0.2 - 0.6). Cant wait to get the intercooler setup..

 

yeh, I'd say your right on, stop all these damn threads acting like you don't what the hell you are doing!

I have had a long time to perfect my street tune, so with that said, there wasn't much more to take from(or give) it on the strip(@MIR). My screw up at Hagerstown was IAT advance table. I didn't have the PID on and I had some crazy *** numbers in there. Didn't dawn on me. I was running down the track with 8* of spark. It was hot out, but jeesh, I was losing 10*. WTF?!

I am glad to see you are on it.

Justin, I am actually just now working on getting my OL table to reflect my commands. I have been trying to get the ve table to where I want it with the commanded 14.68 but going positive 3 to 4% in the crusie areas, on purpose. Now I will try to tinker with the OL table to get the command to match what I am actually getting now. (Obviously adding the 3-4 back to the ve but taking from the OLFA. I enjoy reading all of this technical versions of tuning from you, chris, Flyer, or whomever...I am so laimen at this it's fun to see how I mis-interpret errr not mis-interpret but use wrong words or terms. LOL You guys store to much info. Get Chris rolling about Cylinder Charge Temperature. LOL I gave up on that ****.

 

Yep, 10% just to get him started in a richly safe tune After 10-15 minutes of driving around, he can have that MAF calibration down pat. Did a full VE and MAF on an 01 Tahoe this weekend in about an hour, Jim's MAF alone should be cake.

 

Are you running in SD mode? or MAF'd? Does HPT have the ability to adjust the RPM threshold for airflow calculation (the point where VE is no longer used for fueling)?

 

I am 2bar. No MAF, I even unplugged it (IAT in Radix). No LT's. Turned those off as well. My hugest struggle is what APPEARS to be different temps. Heat soak doesn't bother me too much as once you get driving it all is back in line. What bothers me is what appears to be heat soak, but just isn't. The IAT and ECT are all in line, but I am showing lean, real lean, for a few miles after a restart. Lean below the 105kpa line. Anything above that is handled by pe/be correctly.

 

Very soon i expect my engine compartment to go from this..............



to this................



Oh, its gonna happen....the funds are almost there. I figure by the time cool weather gets here for good, I will have my intercooler....LOL

 

If anything your trims should be rich there is an after startup enrichment until ect comes up. Id log your fuel multiplier and when the engine is cold it shouldnt be 1 if it is then thats what Id look at.

BTW: nice looking setup 496 are we gonna have any before and after dynos?

 

If i get my tune dialed in, i think i will get it dyno'ed before and after if i can work out a decent deal with the guys over at FBC. What kind of gains do you think can be made from cooling the IATs 100*?
