Would be difficult.

That is one of the early hot-wire type MAFs. The wire needs to be cleaned from dust regulary by a "burn-free" function from the DME. The 951 DME does not provide this function.

The newer HFM5 MAFs are based on hot-film technology and do not need any special cleaning procedures.

This is a great system.
I had another system that was fully custom made with the highest level of tuning capacity, huge MAF, SMT... a good system.
The Scivision is a better in everyway and no less in performance compared to the other units.
I have a full custom k27 that flows at least as much as a LR super75, full exhaust... and with this system and Russels chips the car runs great.
This system can handle any modification all the other MAFs can with the advantage of simplicity and no drivablility issues. The car runs like it did new/stock and I should know as I have a 944 turbo bought brand new and another one that has under 60K miles.
You will have no regrets and its nice to have a German part that looks factory stock under the hood.

Tom (Transaxle) quotes 360-380 at the crank.

Oh Oh...........

I have had one of these MAF in my S2 for two years.
As far as reliability is concerned I drove about 30000 km (~19000 miles) in all kind of road and weather conditions with no issue whatsoever.

Hi Russell,

Sorry you have been getting enquiries about some of our products. You are correct, ProMAX Motorsport no longer carry the SciVision MAF product anymore.

We do have very comprehensive fitting instructions which anybody is welcome to download from the ProMAX Motorsport website (links provided for information only).

For 944S2: http://www.promaxmotorsport.com/944s_maf.pdf

The SciVision product is an excellent concept and I am glad to hear that Russell has been able to offer the solution at a more competitive price.

Hey Andrew,

Long time no type!

People just associated the Scivision with Promax because you carried it before and they assume an association with other Promax products. No problem, just wanted to clarify.

Thanks for the install links, if you don't mind I'll use those on my support forum.

Regards,
Russell

One potential solution to higher HP applications of this MAF is to increase the diameter of the sensor's holder through which the air passes. Correct me if I'm wrong, but as I understand it, the HFM5 sensor, or any MAF for that matter, is calibrated for a given voltage corresponding to a mass of air passing over it. Since any MAF is only sampling the flow of air that passes over the sensor and not the entire flow into the engine, the voltage output of the sensor is a function of the air sampled, not necessarily the flow into the engine.

By increasing the MAF diameter, the ratio of air sampled to total air entering the engine would change, making it possible to flow more air without maxing out the sensor's voltage. It would require a recalibration to adjust for the increased flow, but a simple flow bench measurement should give all the information needed. Just a thought...

This could be a Scivision StgII?

Tom has also stated that the kit can be adapted to other MAFs, so as soon as I get specs on all available MAF sensors for the kits I'll post.

Russell

Russell, you are most welcome to use these also.

I just added another package to the offering, on the website there is now the option to purchase the Scivision alone, with 951MAX DME III, or 951MAX DME I Booster chips. The price with the Booster chip is $899.00 USD.

For the record, I wish you had posted this last week before hacked up my engine wiring harness for the LR MAF install...

Andial951

Ok now I'm confused. The Scivision MAF can be adapted to another MAF? Does this mean I can yank out the sensor in my LR Stage IV MAF and put it in the Scivision MAF and THEN be able to run 400RWHP?

Andial951

hey.......just for the record........I wish you would come back and install my turbo...............
