Regular Protege & Protege5 FS-DE ECU
or
MP3 ECU

 

According to SCC, the Callaway cars turbo'd the existing MP3's engine. It is not specific in the test about the ECU. The way it is worded however would imply that it had all the MP3's upgrades before they bolted on the the turbo (the exhaust, the slighty different intake manifold, and, of course, the ECU).

 

Based on the C&D review
Mazdaspeed Protege

I would say it is an modified MP3 ECU, but I could be wrong. (What the hell is Visteon? )

 

I don't know, but this whole thing bothers me.

If in fact a Mazdaspeed protege uses a stock MP3's engine with all the little upgrades and is claimed at 140hp and 142lb/ft of torque before the turbo, that is a gain of around 30hp and 13lb/ft of toque from 6.9 psi of boost. what is that? I am going to stop thinking about this until someone can verify what ECU it uses whether is be its own, the MP3's, or a stock ES's.

 

yes but the MS ecu was programmed to accept the boost...what is FM doing to the P5 ecu??...probably using check valves or something similar...just a reliability issue but still.........

 

Just to clear things up a bit, Flyin Miata's P5 gained a more power with the MP3 ECU installed on their Project P5. The gain was due to the MP3's increased timing, but that timing increase also caused some pinging on the dyno. So it's safe to say that an MP3 stands to gain more from the bolt on BEGI kit. To date, the FM Protege kit does not use any piggyback computers. Here is what the kit comes with.....

Operates at 8 psi (dyno runs to come)
Garrett T3 water-cooled turbo with integral wastegate
front mounted air/air intercooler
recirculating blow-off valve
cast iron manifold
all emissions controls are retained
all pipes powdercoated black
colormatched silicone hose connectors
FM boost gauge with white or black face and pillar mount
BEGI rising rate fuel pressure regulator
early October availability

I think a J&S Safeguard would help a bit and maybe a better looking intercooler. Nothing wrong with theirs in my opinion, but other seem to like an APEXi Delta Fin styled intercooler which keeps optimal air flow to your radiator.

 

Apexi said it, the Protege 5 w/ turbo made more power with my MP3 ECU than with the stock one.

And it pinged on the street in fifth gear w/ the A/C on...Nothing really significant happened on the dyno, no pinging heard there. The MP3 stands to do fairly well with the FM Turbo on it.

Now, their Protege 5 did make more power than w/ the MP3 ECU when they put on the exhaust. It made a big difference going from the puny pipe to the cat-back 2.25" that they put on. So, the comment about the Protege 5 ECU making more pwoer than the MP3 ECU is technically correct with the exhaust added.

They put the exhaust on after I left, so they didn't have my ECU to change out again and test with. However, I am willing to bet that w/ exhaust and MP3 ECU, it would make more power still.

 

so would the begi pressure regulator be similar to a Vortec 12:1 FMU??? wnat to know for myself when i to a turbo

 

Yup, more power from the MP3 ECU for us. But more pinging. No surprises either way.

I would expect the MS car to use the stock ECU or perhaps a modified one - but not an MP3 ECU. I would actually recommend that anyone who wants to turbocharge an MP3 should swap ECUs with a normal Protegé. At least, if they're stuck with 91 octane like we are or they want to go over 8 psi. We didn't show Chris the 110 gallons of race gas in the corner of the shop

APEXistud - do some reading on intercooler theory. It's better to have lots of short passages instead of a few long ones, as in that IC you pictured. More efficient. The Delta Fin should ideally have the end tanks on the top and bottom with vertical airflow through the IC.

So far, at altitude in the desert, our P5 has stayed nice and cool.

I knew there was a reason the Track Dog was parked in the way...It would distract me enough to not notice the real gas hiding back there.

Darn the luck! I'll bring a spare gas can next time...Next time...

 

Visteon is a division of Ford. They make engine and transmission management as well as climate control stuff. We have a Visteon computer in our cars. The easiest way to identify it is by the single bolt going through the center of the ECU main connector. The Japanese units have several shorter connectors instead of the one single connector.

 

Visteon also did stuff for the Panoz Esperante GTR-1 (Ford motor and drivetrain components). I believe they have also done work for Audi on the R8.

Well, at least both cars have huge Visteon stickers on them.

 

Visteon is no longer a division of Ford, they spun off last year. They are now their very own company! whoo hooo...

 

Don't quote me on this but, if you read maximum boost by Corky Bell, I think the FMU is the worst way to run a turbocharged or any forced induction car. Just a personal thing here guys.

If you havnt read that book READ IT!!!! Kieth over at FM sells it but you can also have B&N order it for you. I think it ran me about 35-40 bucks. Its pretty good and gets a little techinical so re-read the tough parts over and over.

Hmm - you must have missed the bit about draw-through carburetor systems Nothing quite like fuel going through your turbo....

One of the ugliest things I've seen was a relay and a resistor wired into the temperature sensor, triggered by a boost switch. When you hit boost, this would make the ECU think it was colder outside so it would richen the mix a little bit. Totally binary and pretty much useless.

Maximum Boost is an excellent read. Corky's got a book on supercharging as well.
