I Emailed Cajun about this chip heres what he had to say.
"It will work, if the chip is an X14 or 4 Bank chip. If it is not, the car will not start. We charge $50.00 plus $8.95 shipping for a
re-program. That is if the chip that you have is of the newer style, Diablo changed chip bodies about a year ago and we cannot program the older chips. There is really no way to tell which it is????
I'm not willing to take the chance. After shipping to them, reprograming (if it can be done), shipping back to you, it would be easier to buy a new one. Hope this helps
i've still got a lfq0 laying around but got a new computer with the lfq1 and it didn't work when i put it in. maybe some day i'll get it reprogrammed for my nitrous but for now it's just sitting around collecting dust.
