SSminneapolis Posted October 17, 2004 Report Share Posted October 17, 2004 knock knock... so i got my lfts all in line...timing table taken care of...O2's are looking good at WOT. but, when i mash it while crusing i am having a KR problem. a while ago deezel suggested manually downshifting...that did the trick...no KR. works every time. my ? is, how do i go about solving this problem with the TCC apply/release settings? other than that, the SS is running like a raped ape...

deezel Posted October 17, 2004 Report Share Posted October 17, 2004 TCC settings to combat false KR... marc_w's suggestion of increasing the normal TCC table by 5mph in the low-mid range seems to work ok. Originally I had only raised them 2-3mph. I ended up tweaking it a couple more times just to get the lockup where I wanted it in the 45-60mph cruising range.

marc_w Posted October 18, 2004 Author Report Share Posted October 18, 2004 Yeah, just a follow up on the PE and timing stuff. I've just changed my PE delay to 1.0, delay RPM to 1,000, and set my PE enable vs TP %, vs RPM: 90 90 90 80 80 80 80 75 70 70 70 65 65 65 60 60 60 60 60 I'm still running that modded f-body table, and I hit 28* at 5,000, maxing out at 31* at the 5,800 shift. 02's were fattened up a bit to a consistant 890-900. No KR at all. The tone of the motor sounds nicer - not quite sure why, but it does. I'm happy I'm making progress! I can post the HO timing table once I get things pretty well straightened out.

marc_w Posted October 18, 2004 Author Report Share Posted October 18, 2004 MAP enable = 15 (f-body style)Hysteresis = 5 (stock, but yours is 6, also stock???) <{POST_SNAPBACK}> I didn't touch any of this stuff yet, but yes, what I posted above here was stock for my truck...

SSminneapolis Posted October 19, 2004 Report Share Posted October 19, 2004 made a few changes and have good results... modifying the kr attack rate and recovery rate...just cause kr is a pain in the arse...also made a few changes to the tcc apply release table and got rid of most of the kr from downshifting... in my last log of the evening it got 2 instances of very slight kr on downshifting at a certain mph...above that or below that i did not get kr....so for now, i am just going to try not to mash it at 70-75mph....i am going to drive on what i have for a while just to let things settle out and such then go back and see if i have any problems...maybe add a touch more timing here and there. thanks for the help guys...

deve8edsilv Posted October 21, 2004 Report Share Posted October 21, 2004 ok ok--i am by no means a "TOONER" (haha) but i was watching and listening when the shop was trying to tune my truck. it was on 5psi and i wanted to run up the boost, and did--but it didn't make any more hp. the guy said he couldn't get it to run anymore than like 10* and it needs like 20--he changed all of the tables he could like EQ ratio vs. rpm timing modifier and nothing....help!

What was the AFR? What was the IAT? What was limiting timing to 10*? Link to comment Share on other sites More sharing options...

deve8edsilv Posted October 21, 2004 Report Share Posted October 21, 2004 supercharger. a/f was 11/1. i am not sure on the iat. don't know what was limiting the timing. only mods are the kenne bell supercharger and exhaust. Link to comment Share on other sites More sharing options...

With some tweaking you can definitely beat 10*. Link to comment Share on other sites More sharing options...
SSminneapolis Posted October 24, 2004 Report Share Posted October 24, 2004 update on WOT timing... i ran a log yesterday after adding a bit of timing...at WOT i saw 30-34*...the 34 was right before the 2-3 shift...it averaged out at 31* at WOT. O2's were 880-890mV. no KR (finally )...running very strong. with the wet roads yesterday i was getting the tires to spin on 1-2 and 2-3 shifts a bit...i'd start out in the left side of the lane and by 50mph i was towards the right...
