I can't believe my car came with a ape dme chip but no klr. Does anybody have a spare klr chip for sale? It could be from any company as long as it has the over boost protection removed. Thanks

WOW thats freakin weird... i just found out 2 days ago that the same thing happend to me... Had ST open up my dme and klr and i had a euro products chip in the dme and no klr chip!

Jimbo, if you are not using the CV it doesn't matter which KLR chip you have. Why do you think you need a aftermarket one?

Ian Carr

Because if his waste gate is shimmed by chance or if he is running a boost controller the over boost protection will kick in and it will send him through the window... Not to mention with a aftermarket DME chip (set for 15 or 18 psi) he will be running rich if he isnt running more boost...

But you know more than i do so i guess you dont need one...?

Hint: KLR only controls the cycling valve. The rest of the overboost protection is in the DME.

Hence, jimbo, you're fine so long as you aren't using the cycling valve (which I can't imagine you are.)

I thought the overboost protection circuit resided in the KLR (along with knock protection, obviously) and upon detecting either the KLR simply sent a signal to the DME, which will then kill the fuel. Is this correct?

Thank you John.

I have one I'll sell. It cost one miillliooon dollars.(austin powers, Dr. Evil's voice)

Who knows why some aftermarket chips have changes in the KLR code? And they were not intended to use the CV.

Dark Lightning

I'd expect they altered the KLR's cycling valve code to achieve higher boost, but if you're using your own boost controller it's a moot point.

Hay Evil. That would be the third chip I have received from you. The last set is probably still in the side door pocket of V944gods car. Who would have known I would get the bug again for another 951.

If what john says is correct than why am i experiencing over boost protection with a aftermarket dme chip and no cv? I think it's overboost protection because when I run less than 1 bar I don't get a buck under large load in fourth gear. Once I go to 15psi it kicks in. It feels like fuel is being cut. Could it be possible that the dme chip I have is a stage 1 ape chip. That does not have overboost protection over ridden. The klr manifold line goes to the klr. Wouldn't that mean that the klr chip is what sends the overboost protection signal to the dme for fuel cut. I am aware that the dme cuts the fuel but with out a signal from the klr it shouldn't cut fuel.

Dark Lightning

The DME doesn't need a physical boost pressure signal. The DME uses the AFM signal to determine the volume of air entering the motor and from that judge an approximate boost level based on stock airflow characteristics. If you were to do a port & polish, over-bored throttle body, swap cams, swap turbos, etc. you'd hit fuel cut sooner since you'd be flowing more air at less boost.

Again, A+ for John (it must be the name ).

I try. *bow*

I have personally hit over 340 rwhp with ape stage2 chips on my other car. Without fuel cut. The only differents is that I had a klr chip. Please explain to me how that is possible when the load was much greater than what this car is seeing right now. When this happens the afm voltage is at 4.1 volts. It's not even close to maxing the meter out. If you guys are correct I just don't see the missing link. In any case I would still want to try a klr chip to confirm my beliefs. Evil you have a pm.
