sd tune on a 98 firebird Is it possible to put an sd tune on a 98 firebird? A brief run down of my setup is a lsx block, large solid roller cam, super victor efi and a fast 4150 throttle body setup. i want to leave the 4150 open with no filter or maf. i was told by a reputable shop around the chicago area that it cant be done. i was told i would either have to convert to 99+ ecu or put and maf. any suggestions?

I'm just getting started so I'm no tuner but i will tell you that I have a 98 T/A and am driving my car on a SD tune and it runs fine. I dont know if it has something to do with your mods like the throttle body.

What he said ^ Which is why it would be a little better to go to a 99+ PCM... but it can be done on the 98. Is it strictly a track car? If it is, or even a limited street use car, I would just leave the 98 stuff in there and use it. Not like you need low octane tables on a car like that... My 2 cents...

i thought it was possible but i was told not. i went with their advice and changed the setup a lil. it now has a carb hat routed to an maf then to a lid. car is primarily track car but i do drive it on the street also.

I have a 98 as well. I just changed over to a 2002 pcm. I was having trouble with the 98 start up and WOT, now with the 2002 PCM all problem are gone. I would def sugest a pcm swap. It can be done with the 98 bit it will take more time to get it right.
