bad guru

I have spent the last five days trying to figure out why my car will not start. It had no spark. I found out that the klr chip was bad. It is a guru chip. The car was running fine and parked it for an hour and never would start again. Has anyone else had problems with their chips. Are they suitable for this application. I guess I am asking are they of the right heat range or are they just junk chips.

Lots of people have had problems with Guru chips, but never heard of a failure. You can run the stock KLR chip if you bypass your Cycling valve. That is how most vendors are doing it now. Just bypass the Cycling valve and you will have a little better responce as well. Good luck.

That could also be cause by a bad DME. That happen to me. When to the carwash, stop to vaccum, never started.no spark. Check my CK sensor, it was fine. I check the harness, it was fine. Check the DME, smell funny. I got a newone, Problem solve.

I program the same chips (2732) in my business and even though we pay top dollar for top quality, occasionally a brandy new chip just takes a crap. Not much anybody can do about it. As for chris951's DME crapping out after installing a chip, maybe it was the chip (unlikely, I've never had a chip take out a circuit, usually the other way around) or maybe it was that the 20-yr old circuit board didn't take the surgery well. They are plagued with bad and marginal solder joints. A slight flexing can make a connection weak, causing high resistance at the connection, causing heat, causing failure a short time later.
People may have some gripes against Danno, but this shouldn't be one of them. He doesn't make the chips and no way the program in the chip can damage your DME.

No, Black944Turbo is right, as long as the cycling valve is disconnected, you don't need a KLR chip.
It is the DME that cuts fuel over a certain load (boost).

I've had a KLR chip fail in the past - in this case from AMD. As Deitz says, these chips are 20 years old and can fail whether they're in a Porsche or computer or even a washing machine ! It's old technology running in a hostile (vibration and heat cycle) environment.
As an emergency, you can 'link through' the KLR by connecting KLR pins 9 & 16 ignition in to ignition out - or - pins 21 & 32 on the DME. This will bypass the KLR, allowing the ignition signal from the DME to loop back without the KLR providing ignition cut or knock delay. I've driven my 951 like this on many occasions.
It can't be denied that these cars are getting older amnd components will fail, looms deteriorate etc.

I know it was the chip because I have two brains and and the stock one works great and when I put that chip in it won't start and vice versa. Is itreally o.k torun a stock klr chip. I nolonger have the cycling valve but I am running 18psi?

FWIW:
I bought the Guru chip kit ($300) in 2003. It included a Dme and KLR chips for 15 psi, shim and reliaboost. I installed it and it worked great. Good low end torque and kick *** top end. A few months later (2003) I have been reading on RL about his new 18 psi DME chip for a while, when out-of-the-blue, I get a new 18 psi DME chip in the mail: free upgrade. I pop the chip in and crank up the boost. Rock solid 5.0 sec 0-60 car. I had the head off 2 yrs ago for a valve job and the combustion chambers looked just fine. I don't know Danno from George Bush, but my car runs great, street and track.

Vitesse chips is only the DME chip. So anyone that says there is a problem running stock KLR chip should talk to john and other vendors. I have been running my car with Vitesse chip and no problem. Stock KLR chip. The only reason they suply the KLR chip is for the boost cut that the cv will provide. Have fun.
