[QUOTE=decipha;584659]trans is all driver specific whats perfect to one driver can be horrible to another
if its all stock then no need in getting crazy with shift points and lock up etc... What I do on all my auto tunes is lock the converter early and use the steady state slip table to dither the converter clutch. It can give you significant tq increases for daily driving and make the vehicle much more pleasureable to drive. Play with it and see.
If you have access to the tq modulation timer functions you can significantly reduce them and increase the tq reduction on shifts to get a more sportier and firmer shift without messing with line pressure. I do that on all my auto tunes as well.
If the car is pinging then it has too much timing for the condition. if it occurs at higher air temps then you need to go to the iat spark retard multiplier table and pull more timing out at the cells its pinging in.
When I used to tune the state local and county crown vic cruisers years ago they all would ping as well when warmed up while running the stock tune so thats not abnormal although our local PD runs 83 octane fuel which is garbage.remental changes to one or two things at a time and make sure they work before doing anything more.
@Thatwhite
Should I make there?s adjustments? The other guy says he don?t touch line pressure.
We all tune different. I like firm shifts, Trans will last longer. A slow smooth shift is slowly burning the trans/clutches, decreasing life expectancy. If yours is high milage it could be hard on the Trans.
When I was younger I had an 04 crown vic.. Had a badass sct device with a canned tune. That canned tune blew my Trans, lost 1st and 2nd and reverse I believe. It wasnt the pressure, it shifted my car too high. I want to say closer to 6800. It sure didn't last longer than a week. I think pressure will help, high rpm is the death.
2011 cvpi ORIGINAL trans tune.hpt
rev limit and trans tune
what is your mods and fuel
I?m going to upload my tune and my data log later if you could take a look at it? I have this little weird issue currently at light throttle and only at light throttle where one to two shift is fine but during 2nd. the rpms dip then rebound b4 shifting into 3rd without changing throttle position
This just started after uploading this tune 2 days ago.
I also agree that higher RPMs destroy these transmissions I think It actually starts by destroying torque converter 1st and then everything else goes from there
My converter for example was replaced a few months ago and its already burning up because it doesnt want to stay locked up anymore. Especially uphill
I also had it shifting at like 6000 RPMs
I did Because after the car shifts out of first at wide-open throttle the RPM needle falls back to about 3800 Before it continues climbing in second. But when It was shifting at 6k. Rpms would fall back to 4K and start climbing. which I liked better. It?s sounds so much better when the converter locks up at 4000k.
I noticed the local Crown Vic patrol cars back when I was younger because I?m in my low 30s now but I would hear them go wide-open throttle and I could tell by the sound of that motor from the outside that After they shifted out of first
They starting pulling 2nd at 4000 @ stock shift point. at the leasat it sounded like stock shift point as you can tell if it?s 6000
Car screams too long. Wish I knew how to accomplish that but that would be nice
nope, if you wants the most hp of your engine shift around 6000 rpm if the car have few mod
bolt ons shift around 6100
4.6 screams loud at high rpms its normal that engine have a nice tone
if your tans always blow up you have problem with your set up
i saw your in your profile your rear tires 275 that overkill on stock 250 hp car that put a lot stress on trans
i have few friends and my car our cars bolt ons we shift like 6100 rpm with trans tune
sorry for my language
To my understanding, You want to edit the Borderline Spark table and raise the mbt to be higher than the borderline, The car will apply the lowest values between those two tables, Reason for raising the mbt is so you only have to tune the Borderline and dont have to worry about the car jumping from table to table, And to look for knock you can add the Knock cyl 1-8 (+adv/-ret) & Knock Corrections, and if the car is subtracting it means you have too much timing and need to lower that value, and if its adding you can add more timing, But I'm no expert, Thats just my 2 cents
