I am guessing that you want to set all your 100% TPS numbers in the shift speed tables to equal what you have set in the WOT boxes on the upshift and downshift MPH, correct? And should you also change the 93% values are just worry about 100% only? What effect wound NOT changing the table to match the WOT boxes have on shift performance at WOT (100%)?

 

I changed them to match.

But how many % boxes did you match to WOT? Just 100% or the 93% too? Just wondering how far down I should go with WOT MPH matches...

 

Ryan, I have my 93% set 2 mph below the 100%, seems to work fine. I am however having a problem now with my 3.73 gears and the 1-2 shift. No matter what I put my shift points to it wont shift at any mph higher than about 37. Joel offered some tips but they didnt work. I dont remember what gears you have, but if you have 3.73's and it works for you above 40 please let me know. Thanks.

I’ve got 3.23s at the moment. I will try what you said and set the 93% values 2 MPH lower than 100% and see what that does. I don’t seem to have any issues at the moment getting the car to shift at 42mph on the 1-2. Odd thing is, my TPS table still had my 100% value at 37mph even though my WOT box had been set to 42mph <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

My 3-2 downshift in Normal mode shift speed table was also set 10mph above the upshift MPH <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> Not sure how that happened but I corrected it to me lower than the upshift.

My tranny was working fine even with all these little flukes (except the downshift to first gear was a little slow), but I don’t know if these were stock settings or something that MTI did or didn’t do when they did my tune. I am working with their LS1 Edit tune on my PCM so I don’t know what my stock setup looked like. Maybe some of these changes will help my slightly slow first gear downshift...

 

Chris:

Your car is still short shifting? Did you check the tire hieght setting in Edit? You might try changing the shift points table like discussed here.

I have mine set at 45 mph and I click off 1-2 shifts right around 6700 - 6800 rpm at the track.

 

Joel, Its still shifting around 37 @ 6100 rpm. I have the WOT settings at 43 mph and the RPM at 6600. The Normal and Hot shift tables are matched to the WOT table at 100%. It just isnt working for some reason. I had no problems with the 3.23's, but that was prior to the cam and higher rev limit. I'm quite baffled by this problem as something is obviously overriding the data tables in Edit. I did the PCM reset and everything that you emailed me about. No luck.

Ryan, The wife and I are coming back home (Chicago) in October for a wedding and if you let me know where you guys hang out I can meet up with you one night and check out the ride.

 

Chris, did you change the values for Performance shift? I know we don’t have a button for that, but I changed my values anyway to just be safe.

Before you come up here make a post in the Midwest section and/or PM me. We’ll see what we can arrange <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

 

Joel, I have tried 42, 43, and 44 but not 45 yet. I have been ATAPing my *** off at the track (12 passes) and on the street (over 20 blasts) while troubleshooting the KR problem and with 1.8 60's my 1-2 shift is always about 6100rpm and 37ish mph. I'll try 45 and see if it makes a difference this weekend. My Ltrims are at -5.

Ryan, I made no changes in Perf Shift as all values are set to 255 and as you said we dont use it. I will IM you when October rolls around!!

 

Chris, you are right the table for Performance shift is all 255, but the WOT boxes are set stock to be the same as the normal and hot shift, correct? I just upped mine to reflect what the normal and hot modes showed.

Maybe you need to do some “fuzzy math” like some have with the HPPs and tire height/gear ratios? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Good luck in your next attempt. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> Get in touch when you guys are coming up <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

 

Ah the Perf Shift WOT boxes - yes I always make those match (since I can see them!!) The tire height is still stock. Well actually when I loaded the gear ratio change it changed the tire height from 25.78 to 25.79 but I'm sure that is irrelevant. Do math?? I think NOT!! I'm a jet engine mechanic brother, I can barely count past 10!! HA HA!!

 

Chris are your LTRIMs slightly negative?

What happens if you bump the MPH to 45?

Have you run ATAP to verify this? Log just mph and rpm. Make sure you get a clean launch w/o spinning. If I spin on launch the car short shifts the 1-2.

Any time there is traction loss, my 1-2 shift is very inconsistent. Especially if I floor it from a roll and the tires break free. Then I know I’m gonna get a short shift...

Maybe you should set your rpm point low like 6000rpm, then set the mph at 45 or so and see what happens. MTI had my rpms at 6000, 6000, 5900 and my 1-2 shift was set at 42mph and I would shift at 6400 on the 1-2 with 3.23 gears and stock size tires. But, oddly enough, if I floored it from a roll it would progressively shift at lower rpms. 25 roll downshift to first got me a 6200rpm upshift. 35 roll downshift to first got me a 6000rpm upshift <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> Come to think of it, maybe this was because my rpm was set so low?? Also, MTI did not change the 100% TPS tables at all. They were all 37mph for the 1-2. Don't know why they did that but I fixed it last night <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
