Has anyone done the TSP mail in tune vs. Dyno tuning? There aren't any dyno shops wtih experience tuning f-bodies near me and I was thinking of doing the TSP mail in. I have a bunch of bolt-ons and a TSP 231/237 cam.

Thanks.

 

please wait til u have someone there with the car on the dyno to see what its doing. i already made this mistake once, and i will never do it again. for a real good thorough tuning job, the tuner will need to see what your car is doing all through the rpm band. he can also read your a/f ratio and adjust it if necessary. bottom line, u will most likely and up much happier if u wait and find someone who can have your car for an hour or so.

 

I don't know of any places close to me to tune it. Also TSP made the cam so I figure they would be pretty good at tuning them by now.

 

Thats something I want to know too. There is one shop where I live that does dyno tuning and I haven't too good of things about them.

 

TSP has to be close with there cam that they make with the tune.

 

They did a mail order tune for me with the tr230 ,never had any problems out of it drove it every day but never dynoed it

 

I figure you can get the mail order tune, dyno the car and then send the PCM with the dyno and A/F graph if there is anything else that needs to be adjusted.

 

I was down at TSP thursday to have my car tuned after the cam install, but we decided to not dynotune it yet due to a bad lifter. anyways jason basicly made up a mailorder style tune then downloaded the tune on to the computer all with out ever starting the car and it runs fine, actually it runs great. if you dont have access to a dyno tune there mailorder tune will be your best bet. i have the TSP233/239 and it drives perfect from the tune. jason knows what he is doing

 

69 Yenko, your car have a hard time finding idle when cold? it die when cold?

 

TSP did my mail order tune. My car runs great. I just told them eerything I have done to the car. I have the 231/237 cam in there so they know how to tune it for that cam.

 

Awesome, thanks for the replies guys. I think I am going to send it in and then have it dyno'd when I get it back to see if it needs tweaking.

 

Sounds good. Let us know what happens.

 

When I installed the TR227 I sent Jason my file, he adjusted it & it worked great. I just had to tweak the WOT mixure a little that's it. Now I just screwed it up by adding the ZO6 maf & tables & my ltrims are off & WOT is rich. TSP guys do a good job, before I couldn't even drive it.

 

it surges for a few seconds then its fine, it did die once after backing out of a parking spot and putting it in gear. but i only had 20-25 miles since the tune so i think the computer was still trying to learn every thing. now that ive gotten more miles on it, its running and driving smoother then when i posted earler today, I love it

 

Why or how do you suppose its takes the computer to "learn" how to control it? Is it like a memory type thing or something? I just don't quite understand if the PCM is getting its readings from the sensors, why would it change with time/mileage? I read that they ALL are like this, I am just wondering why? I am just used to speed density type stuff and when its mapped, its mapped and thats all it will ever be. Maybe during the season changes it might run different from the type of conditions its was mapped in but. These things seem really complex. Interesting stuff though. I hope mine runs ok after its done. Having the bitch die on the way to work is gonna suck.

 

Now mine idles ok (about 750 to 1000 but bounces back and forth). The problem I have it when I rev it and it comes back to idle it almost stalls out. It did stall a couple times, but usually goes a little below 500 then back up. It is also very rich. When I start it and let it idle, I can smell gas pretty strong.

I had it in world of wheels and the battery was disconnected for 3 days. When I started it up, it would not even idle at all. You should have seen me trying to drive out of the convention center in a line of cars trying to run the gas brake and clutch. I probably stalled about 7 times. After about 10 minutes the computer re-learned the idle and was ok, but still very rich and not liking the higer revs.

 

And that as dyno tuned or the mail order tune? I will be pissed if mine runs like that. I am assuming I will have a little idle hunting etc but if its parked for 3 days and then runs like **** when I do start it, I'm gonna do something else. Apparently even the smaller cams can do this though. My buddy has a 224/228 in his TA and he said his has bad idle hunt and dies from time to time. WTF?

 

Why can't they lean out the idle mix some for you? It sounds hopelessly rich when cold. Right?
