Yes, the S/S2 kit is the next one, I'm am currently working on it.

What octane of gas are you using?

Mid-grade.

89?

Yes.

Gonna be up for sale soon? Christmas is coming up fast!

How does this sound for an idea: you could make cam keys an option for a few extra bucks when a customer purchases a kit . That way they can get everything in once place instead of having to order stuff from two different places.

isnt a cam gear that is sloted better :D ? prices on theses kits are ? and what the cam key worth

He mentioned that the kit is $500 in the thread over on Rennlist. A cam key set from 928 Motorsports is $38 and you get a 2* and 4* cam keys. An adjustable cam gear is $325.95 from Lindsey Racing. I think I'd rather have the keys....

Josh, on your site it says: "The '86 and '87 years had the "24pin" EPROM, while the '88 and '89 were upgraded to the "28pin" versions." Is that just for the turbo, does the 85.5 + NAs have the 28pin or 24pin??

86 to 88 Conversion ML3.1

What about the early cars? It's not totally clear to me what I would need to do to install this on my '84 944.

Thanks for the link.

From the link: The Change was made by BOSCH in late 1987 but is referred to as the 88 redesign. There is much confusion about the 1988 DME and much of it is nonsense. The memory size is the same as the 86 DME. In 1988, the 4k x 8 EPROM was replaced by a 8k x 8 EPROM. The 24-pin socket was replaced with a 28-pin socket. The final change was to add a jumper to the board that instructed the 8051 to ignore its internal 4k x 8 memory. All 8k x 8 of memory is now stored in the EPROM.

Yep - I received the first batch of MAF pipes. I will do some final testing this weekend, and should be putting up the order page next week!

Having an option for including the cam-key is something I think is a good idea, and I am currently pursuing. I will update as soon as I get something solidified.

Exactly. The cam-key does not have the fine-tune capability that an adjustable cam-gear gives you, but it gives you the majority of the gain for ~1/10th the cost. You just need to test which combination is best, and fortunately, I did that already and you can just use the info/data that I've provided. :cool:

I believe the switchover is the same for both the turbo and non-turbo 944.
Yep, the upgrade is not significantly difficult. I offer the conversion as a service. Additionally, when I convert a DME, I do go over the typical trouble-spots on the DME board. (requires fully removing the boards from the case)

For an early car (my 944NA is also an early model), you will need a late-style DME (and converted to 28pin if it isn't already), and the NA-Tune. That is it, any other requirements are part of the kit.

Yeah - a lot of wording to simply say that with the 28pin DME we have access to all the software, unlike the 24pin units. Full access is needed, as I rewrote (software) the part of it not accessible on the 24pin unit.

OK, that's what I thought. So just to clarify, is the "late-style DME" 85.5-up?

Yes.

Another quick update, I contacted 928motorsports and confimed, so I will be offering the 4 degree offset key as an option with the NA-Tune!

Novice question. PO replaced factory airbox with a custom made (nice job) bracket and a K&N filter. Does this negate the installation of your unit or effect its ability to perform in any way? Thanks.

It shouldn't affect the installation. Your PO must have used an adapter to bolt to the stock AFM. My MAF is designed to bolt-in right in-place of the the stock AFM. So it should still physically bolt-in.

That said, the factory airbox is a really good piece. There isn't any measurable restriction at our power-levels, and it pulls cold-air from the fender-well. If your K&N filter is in the engine bay, then you are sucking-in warm engine bay heat, which is probably reducing power.

This may be a dumb question, but the timing on my '90 S2 has been advanced (4 degrees?) - does this accomplish the same thing as the cam-key discussed above?

Would this be a problem for your MAF kit and software?

Thanks! Looking forward to this...

Where the confusion is typically due to not differentiating between ignition timing, and camshaft timing. The two are separate, and on our cars, one does not affect the other.

Adjusting cam timing (within reason) is not an issue for the MAF kit - that is exactly what I did on the Dyno.

Also, just a clarification, the current MAF kit is only for the 944NA, the S & S2 are something that I'm working on, but will be a different kit.
