2.7 Motronic Tuning Source?

No one or we would have done it already.

 

I think Fabspeed does a package upgrade that involves some kind of ECU tuning even for 2.7, heard from someone with their 5.2 ecu upgrade that was happy with performance:

The only guy I know of who is good at tuning the Motronic 2.7, in So Cali, is Steve Wong.
911Chips.com - Porsche Performance Chip Tuning
Only thing is, last time I talked to him about tuning, Steve hasn't tune the Motronic in a Ferrari. His specialty is tuning Porsches. None the less, he is the guy in So Cal for tuning a Motronic 2.7. It won't be cheap though. He will have to figure where Ferrari put everything in the code and hex files. Then there is dyno time, plus his tuning fees , on not one but two Motronic ECUs = a few thousand dollars when all is said and done.

 

I had a piggyback computer put
online wth the stock computer. The timing and fuel can be changed with a laptop. No need to crack the Ferrari code.

 

Got a friend europe with a twin turbo 2.7 that is running 2 bmw ecu's. Next time I am out that way I will have a look see and take notes

 

Well spill the beans man. What was it and where do we get one?

 

Two unichip Q+ computers that intercept the signal before it goes to the stock computers.
They were mounted under the stock computers and spliced into the stock wiring harness.

 

Scudaria Rampante posted that they had an upgrade that produced so much more power that wheel spin was a problem, but never responded to questions about what the upgrade was, and never mentioned it again.

 

I offer an ECU tune for the 2.7 and the 5.2 Cars. Here is a dyno graph of a 2.7 355 with our exhaust and tune

Do you do your tuning while it's on the dyno Evan?

 

This is an ECU tune as opposed to a Dyno Tune. The management that the car runs on would need to be significantly tweaked to be able to tune some of the smaller parameters that make up for a larger change, in real time.

This ECU tune uses your factory ECU and we upload a proprietary tune for your car onto your ECU. The tune is specifically adjusted to take into account things like fuel octane, modifications and driving atmosphere (road, track etc.) so that you can gain not only the most performance out of the tune itself, but also so you can gain the maximum performance out of any modifications you have made to the car.

 

I see, thanks for the reply Evan.

 

I think the only way you could dyno tune would be to use chip emulation via ostrich or similar (and you'd need two of them). That or use eeproms and tweak/erase/burn repeat and then burn the final tune when done.

I've looked into it but I don't think the juice would be worth the squeeze unless one had already upgraded the brakes, suspension, tires and the exhaust. I still have the brakes and exhaust to go before it'd even be worth looking at.

 

Mine was tuned on a dyno after headers and Goth exhaust. Laptop connected to piggybacked computers

 

Jim Conforti used to hang out in the 360 Forum years ago. Someone might try sending him a PM to see what he came up with. Jim is extremely well known and respected in the BMW world as the inventor of the Shark Injector, a OBDII port flash programming module.

 

After the tune, do the piggybacks stay in place? I'm guessing they do.

Do you have any pics of how it's hook up?

 

If you take them off, you end up with the untuned ECU running things.

 

They are mounted below the stock computer. They are fairly small and thin. Plug in your laptop to change parameters of fuel and timing.

 

Comforti seems to have given up on us. I've tried to reach on this subject before.

 

Well it seems the Unichip Q is gonna fit the bill. Next thing is to find a tuner.

 

I can't imagine larger injectors would be necessary with just some bolt on mods.

 

Let us know what you find, though I don't really want to be at the mercy of a tuner. Just got some Eproms and my buddy has a burner, so I'll be doing some diving into the engine mgmt. files.

 

In the 348 we think that the injectors are at the limit once you do the mods we have. Any flow calculator on-line will demonstrate that even at 95% duty cycle, adjusted for fuel pressure, (not recommended) the stock injector taps out at 330 HP. Theoretically. Therefore, a slightly higher output injector is suggested, even if your goal is 330 gross HP just to drop the duty cycle which reduces heat and prolongs injector life.

This has been the SOP for tuners such as Steve Dinan on his upgrade packages for normally aspirated BMW M3's (which I once owned). With an exhaust and intake upgrade, stock injectors needed replacement in his packages along with his chips or flash (depenidng on model).

For comparison, my M3 had almost the same mods that I have on my 348 and it made 20% more power. I do not have these gains in mind for the 348, thinking that Ferrari left less ponies lying around the factory floor than BMW. The weak link, however, continues to be the lack of a tuner for the mods. Once accomplished, I have no hesitation at seeing additional gains to what we have realized to date plus a bit more, added to a much better fuel map than stock.

My co-Stooge thinks he is going to find a lot more HP while my aspirations are more modest. We shall see. Either way, the Brotherhood is going to directly benefit from our machinations since we always support our efforts with dyno runs and freely explain what we do, how to do it and where to go for the experts.
