senior moment . Ls1 stock VE & timing tables 98-00 vs 01-02. what to use after swap?

[Stuffs]

i feel a dumb asking this but just did a cam swap and a 411 pcm swap to a 98 bird and has a 02 camaro/firebird (156) file. Car has stock 98 engine, 806 heads,ls1 (egr)intake, 1 3/4s headers ory and now the mentioned cam above is a 231/234

my question is what VE and Timing tables to use as a base to start tuning ? do i benefit from the 98 timing that seems a lot more aggressive than other years using this bumpstick? or ill better stick to the safer 02 table. also ve shape is totally different in the 98-00 than the 01-02 bigger ls6 intake equipped cars... is it just the intake that changes everything? i think year after year calibrators fix and upgrade some things and being a ls1 intake car i can stick with a '00 file numbers. what do you think ?

Since you already had it tuned for the cam use the 98 VE table and timing so it will run correctly and tweak from there.

it is not tuned yet , cam and pcm swap at same time

the STOCK 98 file or the STOCK 02 file? , car has not been tuned yet, zero.i want to know which calibration is better ground to start with.

i will rephrase que question

i have a 98 car with a new cam, do i benefit from the 02 calibration to start tuning? it has a lot of differences on basically the same engine/sensors with another intake.

go with the one that suites your goals and OS availability

lol.....I would go with the 02 as it is more compatible with the PCM. Also I always liked the 02 timing table, use it alot as a starter table. The 98 file/PCM are very archaic compared to the newer and more powerfuly 0411 PCM.

thanks Ed for the fast reply , lol

and what about the VE? does the intake make all that difference?


congrats on your new site BTW

Never really gave it much thought, but yeah I guess the manifold and the 78 to 85mm TB made them breathe a bit better.

Thank you for the props on the site. really excited about this venture and have several customers already. Also some exciting news is coming in a bit......:-)
