Why would fuel issues at WOT cause it to back off timing (i'm guessing that is waht was happening) even at the slightest touch of the throttle? I couldn't get any revs at all, once the car warmed up.

weird theses are the same problems i am having with the same chips. as i been on them for months but now my car wont start and i tried everything last thing i didnt check was chips and the dme/klr its self

how can i tell my stock chips apart? idk which is which lol

They have different numbers on them, only differ by maybe the last 2 or 3. I luckily had a spare klr around so I could check which was the KLR and then which was the DME... but unfortunately I don't remember the numbers.

What year is your 951? Found this for an 87: DME 1267355235 and KLR 1267355138 from

If your car doesn't start, it doesn't sound like the same problem as mine

thanks for the link i been looking and turned up with nothing..

my car is a 86 as well. i do get the sputtering at normal speeds/rpm and starts to backfire

it didnt bother me, i thought it was just something else. but everthing checked at fine. (i only drove the car once a week) didnt bother me. but now wont even start, and the dme heats up so bad it will burn your hand if you touch it.

so ill try to change the chips out right now and let you know how that goes. maybe something wrong with the 86's chips?

Thanks, let me know what you find.

The DME is supposed to get really hot...it freaked me out when I was messing with all of this the first time around and just left it laying on the floorboard.

so it is? all the post i read it should be tolerable. not burning hot?

so for sure it supposed to run hot that you can get burnt from it?

im not an electrical engineer but when electronics get that hot usually there's some sort of short (from my experience)

Update: I switched in the stock chips the car started right up. yet it wont rev up fast (like normal) yet if i rev it slowly it will rev up all the way. this was sitting in the driveway yet to drive it. well its not drivable like that.

no, it's supposed to get really hot. I was chatting with John (Vitesse) about this at one point when we were troubleshotting a few issues with my MAF setup and pointed out that my DME was really hot...he said it's supposed to be that way...and even made a comment about how these things will literally be hot plates after a dyno session (as in you could cook something on them).
