how do u tune for a top swap on a 97? You cant run a 97 gtp file, tranny doesnt want to get out of second. You cant run a gt file cant control the supercharger settings. Is there a way to splice the two types of files together?

PCM doesn't control the SC. The boost bypass is mechanically controlled. Your PCM problems with the GTP and tranny is because the PCM thinks you have 2.94 gearing where the GT has 3.29. I would think that if you have access to a tuner you can change the gear settings in the PCM to know your running 3.29s not 2.94s.

we changed the gear ratio settings but its not engaging the 3rd gear solenoid. i know the pcm doesnt "control" the SC. sorry if i mistyped that but there are settings in a gtp file that you can modify which the gt doesnt have...

PM chico on what he did when he pressurized his ride.

Who is doing your tuning for you?

Flash a GTP file to your GT PCM and add the GT tranny settings to it.

Corey thats what we did and it still did not work. there seems to be a hidden setting that cant be changed

Thats exactly what i did with mine. Make sure you got all of the settings flashed on there.

Double check all of your wiring, something might be pinched. Check under the battery, there is a tranny wire that gets pinched a lot, just make sure all of the wires are out from underneath the battery

everything runs fine when the gt file is flashed in.. remember i have the wonderful 97 with the 60 tran a 97 gtp has the 65.

upload your gt file again ... add more fueling, and add timing, curently i just got a new tune the other day and i have a gtp tune on my pcm ....

thats what im running right now so that i can have my gears back.. it sucked driving 90 miles on the hw in second... my turner is checking into things to find out whats up, i just want my car to run right and i want boost. and i thought all the hard work was behind me....

no! dont add any timing. retard it!!! i cant stress that enough. GT's have much more timing than GTP's for a reason. and dont mess with the fueling, just use GTP settings for fueling if youre running L67 injectors

Yah something isn't hooked up right, you have a 97 and missing something, or there isn't something correct in the tune bin file.

well i dont have any way to change it back now

i dont know i just want my belt on and be able to run fine.... its getting so stressful and the guy lives 2hrs away....

Not you, theone.

A GT with a top swap and increased timing is asking for trouble.

i dont think he gave me more timing just put in that i had bigger injectors... i dont think he did a thing with timing

ok i thought u were sayen something to me about me basicly running a gtp tune on my gt with a few tweeks

why did you do that?

well... i went to the junkard and got an extra PCM ... we flashed it with a gt bin file and then tuned it from there, im not sure exactly what tune he did on it or i could just be mistaken from what he said, because i was out roasten tires in his regal when he was tuning my car lol

I never had a problem with my 97 trans. I started with a ZZP tune (which worked fine trans.wise) then I had a dyno tune done ,remember shifting is partially controlled by the vacuum modulator and make sure the modulator is getting vacuum from the LIM not the TB also I would install a new ajustable VM at this time to make sure it's operating properly ask for a modulator from a 96 ssei ,if you can't get things operational contact ZZP and inquire as to their secret.Chico(pops)

sorry to sound dumb but whats the VM chico?

vacuum modulator

ok now where exactly is this located, because i will need to pick one up when i do my ss setup ??

youre fine. The 97's have the partly vacuum modulated trannies. We dont have them in the 98+ cars. Ours are electronically controlled

ok good .. thanks sorry for the dumb question back to tuning

is it worth getting a pre tuned pcm from zzp/whoever or a custom tune?

The VM is located on the top of the tranny. Easy access.

i already have the vm installed since the start of this year. why is it better to get it from the lim instead of the tb? but im starting to wounder if they use a 96 or older gtp file that ran off the 60 trans

cant use an older file then 96 cause it wasnt OBD2 so thats a no go... if your having probs with the setup... you can Email or pm me a copy of your bin and i'll look over it... my 96 Z has the same 4t60e that you have and i have a good understanding of what the settings should be.

....Theone2043.... can you please break down all the mods you have and the entirety of the swap... like are you runing a 2 bar map? what injectors you are runing, l67 or l36 maf, all the details, even if you have exhaust work ect.... from this and the bin im sure i can get you a file that will get your car runing right... if the kid that is tuning your car has access to internet, you can even have me schedule a time when yoru gonna be doing the tuning... and i can take that time off and we can tuning over the phone and email the file back and forth while you are with the kid. dont stress it will get sorted out and you will have a fun fast efficent ride when done.

list of mods i have... the top swap is everything l67, im also running i think 104 plugs

so yeah, is it worth getting a pre tuned pcm or are you better off with a custom tune???

custom tune to your specific car is always better than a generic tune

According to ZZP you need to run the vacuum line from the LIM to the VM so the trans. sees boost and your trans does'nt slip .Chico(pops)

how would u run it to the lim? off the tb i have the tranny and evap. off the lim i have the map, fpr and bypass solenoid. off the tree on top its the bbv brake boost and the havc line. is it possible to live the bypass solenoid vac disconnected?

Do you mean the BBV? You run vacuum to the BBV,remove the solenoid and do not cap the vacuum outlet that went to the solenoid leave this open.

boost bypass valve solenoid

no, don't leave it disconnected. if it's disconnected it will either stay open and never build boost or it will stay shut and you'll never be able to release pressure when not on the gas.

The electric solenoid is not needed for the BBV to function,again you run vacuum to the BBV ,remove the solenoid and leave the vacuum port open on the BBV if you cap this you will not see more than 3lbs of boost.

so i can disconnect the vac line going from the fpr to the bypass solenoid and then run the tranny to the fpr which then goes into the lim. so as long as i dont cap the solenoid it will still preform its job just fine and i will be able to see more then a few lbs of boost?

why not just use a tee? then you're not leaving anything disconnected.

We are talking about what works best with a top swap or SS M-90 setup!!! I find that the BBV (since your using a GT PCM ) and you have'nt got the solenoid hooked up is to remove it and leave the bootom vacuum port open the top vac goes to the top of the SC .

i have the solenoid wired in

OK then it was'nt really necessary but whatever,for the other line that's right LIMto FPR then a T to the VM (trans)
