Re: need help with pcm on ls swap

Here is a link in the classifieds of a member that can program your pcm for a fair price so that you can get the car to exhaust and stuff
https://www.thirdgen.org/forums/lsx-...swap-tune.html

Also among the others, a dude named frost over on ls1 tech can as well. Seems to be well recommended. I have dealt with him before when I purchased a Harlan shift light. Very quick shipping and awesome communication. I hear the same on the tunes on these pcm's!

Send it to the shop that will do your tune and put the money toward the end game.

Re: need help with pcm on ls swap

i am just looking to get a tune to run the car good enough to move it around i hate pushing/towing my car or any car when they don't run it is more hassle than its worth

Re: need help with pcm on ls swap

there are a bunch of guys over on 'tech that do mail order tunes, I used Frost and was very happy with turn around time and his attention to detail

Re: need help with pcm on ls swap

As stated above..many guys on tech come highly recommended.Id also vote that if your looking to buy a ecm cheap with a base tune to run..spareecm.com was great for me.bought my ecm from these guys on ebay..had everything programmed that i wanted..gearing,speedo,rev limit,tire size,tach etc. and then they let me know that it would be delayed as they were busy so they gave me free powder coated ecm what ever color i wanted and it was clear coated ontop.talk about service.Car started and run great.

Re: need help with pcm on ls swap

Iv sent 3 over to speed inc for base tunes and they have all been spot on.

http://www.speedinc.com/services.cfm


As others have said frost also does a great job but iv never personally used them.

Have you talked to the place you plan to have it dynoed?
