Drop-in replacement for Motronic ECU!

911TT33 · 05:23 PM

Just came across this product for all you 3.2 turbo converts out there who want more control over your fuel & ignition maps for your turbo conversions

Apparently this replaces the Motronic DME and plugs into the existing wiring harness.

Porsche 911 Tuning : Canems EMS, Online Store

Gives you FULL ignition and fuel control, and comes with a base 3.2 map to get you going. Not a bad solution

Our fully programmable ECU, combined with the excellent MAP & TPS ignition upgrade kit.

This kit takes takes just one hour to fit, and the results are breathtaking! Much improved thottle response and crisp acceleration from anywhere in the rev range.

No affiliation whatsoever. Just thought I'd share what I found.

whoa that's great!! thanks for the link!!

Very cool but the price is way over the top.

Some of the braintrust on this forum can do the same thing to the factory DME FYI.

Great find!

mamut · 12-07-2011, 08:23 AM

Looks very promising,cheers.

Not really, when you compare it to the likes of Motec or Autronic + significant dyno time to just get a base NA map working properly with cold/warm start enrichment etc... and this ECU interfaces to the OEM loom connector. No re-wiring labour needed, or the mounting of new sensors etc.. OK, maybe just a new TPS sensor if you want TPS to measure engine load, but you can measure load with a MAP sensor and vacuum line to an existing port on the throttle body.

Once the turbo system is bolted on, you take it to the dyno for fine tuning. Any competent dyno tuner should be able to adjust the maps with the Windows UI

Motronic DME - Have to continuously burn new chips and use trial and error. Can you even reprogram the factory DME dynamically? I've never seen any RS232 serial ports on a Motronic DME

I have to agree, you can even get them preloaded with your current map, you could have a fully programmable ecu in your car in about an hour. The pricing I think seems more than fair, I was quoted more than that just for the motec installation (it's something I wouldn't want to DIY) and forget about using your stock wiring harness. Anyway, hopefully they will chime in at some point and we can get some feedback.

My 930 has a Protomotive modified Motronic DME. I don't like the idea of not being able to change its map easily (only by reburning). The programmable ECU looks really interesting! I'm looking forward to hear other's experience with this ECU before I jump into it (if I ever do).

I too have heard good things about the Proto DME, however, it is just a "generic tune" and cannot be tailored to your exact setup easily. Every motor is different and the Proto DME is just a generic tune for a 3.3L efi motor, Calibrated for up to 1.4bar. If you want a precise map, you need to get all sorts of sensor output measurements and AFRs to them to fine tune and burn a new EPROM... Then do it all over again until it's right.

As far as I'm aware, Proto are the only ones who can do it too, because their chips are protected with some sort of encryption. What happens if they go bust, or something happens to Mr. Knighton? That knowledge is lost forever!

Tippy · 12-07-2011, 03:34 PM

I meant that I bet the guys on here can do the same to the DME for next to nothing.

You're paying for the package.

911TT33 · 04:06 PM

Yep, you're paying for the package including software, base NA map, and all the R&D that goes into developing a drop-in OEM replacement.

I'd like to see if and how someone can do the same with the OEM DME with full programmability. I'm sure it can be done, but I doubt for next to nothing.

To install, wire and tune a motec or autronic you'd be looking at upwards of $7-10k

Tippy · 12-08-2011, 07:01 AM

I wonder if our buddies "ischmitz", "Steve Wong", or "Lorenfb" could reverse engineer this and make the components kit for us????

Do like a MegaSquirt type deal where we solder our own stuff together.

There is a business opportunity here!

I'm selling my MAP 2 ECU piggy back as I just don't have the time to install it and mess around.

Also comes with a motronic wiring harness adapter I had made which is a bridge of wires that plugs in between the motronic and wiring harness, to splice into so you don't have to splice into your factory harness.

This thing can do everything, convert to MAP, switchable maps, flat shifting, run water meth, extra injectors, boost control, logging, etc etc.

Cool. Are you going to try out this CANEMS instead?

spence88mph · 12-11-2011, 12:52 PM

That is the way I will go as I don't have time to tinker these days, work and building a house is taking all my time.

89turbocabmike · 12-11-2011, 01:25 PM

This is a great option. If you really look at the cost of stand-alone systems out there, this looks very reasonably priced. Plug and play? I've wired enough systems to appreciate the value of this feature. Many flying lead harnesses alone are in the 300+ range.

Exactly my point! I think it's a VERY good alternative to Protomotive's plug'n'play MAP-based Motronic DME (which costs up around USD$3k). At least this solution gives you the ability to re-tune to your hearts content. With the Proto DME, you have to send sensor measurements back to Proto to recal and burn a new EPROM until you get the tune right for your setup. This ECU can all be done dynamically on a dyno by any competent tuner. Very slick!

Rick Chip · 12-22-2011, 06:19 PM

This looks interesting to me. I was considering the Protomotive setup.

Tippy · 12-23-2011, 04:48 AM

You guys realize the price is in pounds, right?

MegaSquirt is still A LOT cheaper. Of course, it isn't plug-and-play.....

Tippy · 12-23-2011, 04:50 AM

I should add too, what is the hertz of the processor and table size?

I couldn't find it, but I'm using my iPhone.

I have done few VEMS ECU's as P'n'P for both 964 and 993.

Price of VEMS is in Euros, so not very expensive at all.

VEMS is 16MHz and has 16x14 tables, rpmxload and both axis are fully customizeable (whatever rpm/kPA in each loadsite).
