Does any one have information on DME numbers??? or know where to find information on how to identify year and model.

I am trying to figure out what DME I have...... it is supposed to be a 1988 or 1989 turbo 'S' DME but I am not convinced. I bought a 1986 turbo with a turbo 'S' engine in it but I am not sure the DME was also changed.

These are the numbers marked on the boxes:

DME = 0261200052 & 95161812101
KLR = 0261201015 & 95161811301

Any help would be greatly appreciated.

Thanks,
Paul

Thanks.... That is a great site but sadly no mention of how to identify the year/model of the DME.

Thanks,

All KLRs use 24-pin chips. Once you upgrade, the main function of the KLR is to manage TPS sensing, drive the boost-gauge and retard spark when knock is detected.

951.618.121.01 was used on early '86 951 and had 24-pin DME chip
951.618.121.02 used on late '86 and '87 951 and is 24-pin DME chip
951.618.113.09 used on '88+ cars with 28-pin DME chip

Most likely your 24-pin DME is from an '86 951. Not sure how the fuel-maps could possibly match the TurboS engine. The only thing that would come close in a 24-pin package is the Porsche TurboCup chips '85-86.

You can always crack open the box and see what the numbering is on the chip itself to verify.

Thanks...... that was exactly the information I was looking for.
So as I suspected the DME is most likely from a 1986 car (this would make sense as its a 1986 car)

If my engine is truly a 'S' this could explain why my boost gauge is not working!!!! And the car doesn't quite run as smooth as it should.

So how do I now confirm that the engine is really an 'S' motor and not the 1986 one???
I would like to get the right DME for the engine.

Thanks,
Paul

The dash boost gauge has nothing to do with an S vs. non S motor. The main difference (as far as running) between the S vs. non S is the turbo.

The running condition may be related to a different problem.

You don't need to purchase a DME, just use a chip for the 951S that is burned on the 24pin chip. Or get an a performance chip for the S on a 24pin DME chip. (All KLR chips are 24-pin).

If you find a set of 951S chips, I can burn them on 24-pin to work with your DME.

"So how do I now confirm that the engine is really an 'S' motor and not the 1986 one???"

Hmm... I suspect the only way would be to remove the exhaust crossover pipe and measure the size of the turbine wheel.

"And the car doesn't quite run as smooth as it should."

Most likely that's something else other than a chip problem.

I've got stock TurboS maps on a 24-pin chip if you want it, but may I recommend a GURU Chip Upgrade? Got chip-mappings for K26/6, K26/8, K27/6, K27/8, a couple of Garretts in both 24- and 28-pins... <img border="0" title="" alt="[Wink]" src="wink.gif" /> <img border="0" alt="[bigbye]" title="" src="graemlins/xyxwave.gif" />

To figure out if your engine is an S engine, get the engine code stamped on it. Also, on the turbo, it should have a sticker with part #s on it.

You can always upgrade the chip, however, I would try to figure out the exact problem first. As of now it's guess work.. You need to do some more testing.

So if I am reading and understanding everyone correctly....... The DME and KLR is the same on all the turbo's. It is the chip that makes the difference.
So regardless of which DME/KLR I have, If I purchase a set of chips (I am looking at the Guru Chips) and install those then that should be ok.
Obviously I have to correctly identify which engine I have. Does anyone know where the engine ID number is located??? I thought it was on the block but I can not see it.
Once I have found then engine ID number, any suggestions as to where to look for information i.e..... websites etc.

Thanks for everyone's help

try this site. it breaks down the vin numbers <a href="http://www.geocities.com/MotorCity/3322/spec.htm" target="_blank">http://www.geocities.com/MotorCity/3322/spec.htm</a>

The only engine differences between the TurboS and Turbo is really just the turbo and DME chip. I've heard that the head and valves were different, but haven't found evidence of this yet. And it's entirely possible to have a Turbo with TurboS's K26/8 turbo. Or you can have a TurboS with a Turbo's K26/6 turbo.

I have 2 Turbo S engines. I was unable to see any difference in the head, valves, guides.... between he S vs. non-S heads..

I am planing on buying a performance kit from either Lindsey or Vitesseracing so I am wanting to make sure I don't buy the wrong parts A) That I cant install or B) I install and it damages my car.

I have some performance HR chips right now...... they came with the car but were not installed. Do you think I will harm the car if I install them not fully knowing what I have????

Also I looked in the Hynes Manual to see where the engine ID was...... I think I found it but I am not sure.
The numbers I found are M44/51 45J00080
Also the number 944.115.401.2P

Do these numbers mean anything to anyone???? Are these the right numbers to identify the engine????

Thanks.... You are all being very helpful. I greatly appreciate it.

M44/51 is for 951 MY86,87 and NON-S MY88
45J00080 is for MY88

So you have an engine for a 1988 951 (Non-S).

The 951S engine is M44/52...

If you plan on performance upgrades, I recommend you save your money and kit the appropriate chips with the kit you purchase.
