new chip ! new problem !
My 88 had the original chip from GM and my brother`s 89 had the hypertech stage 2 chip ,,So we switched them becouse I am trying it in the quarter mile ! and here is what happend !! Now in my 88 the overdrive light on the digital dash came on and stays on with the hypertech chip, and with my GM chip stays off ...... On my brothers 89 vette with my 88 GM chip has the- 1 to 4 shift light - on the digital dash and with the hypertech chip it stays off!!! What seems to be the problem ???? Are the chip interchangables or NO the engines both runs fine !!!

marlon, we have to remind you that the 89 has the ZF trans and yours has the 4+3? Different you think?
Try starting your 88 with the 89 chip in cold weather, same for the 89 with the 88 chip. :D

Re: new chip ! new problem ! (marlon88)
88 and 89 use different programming masks (88 is $32b while 89 is $6e). Although the cars run fine when they are switched, there are differences in the chips. That's why you see the lights on the dash.
