We are coming out with an EVO IX project and have an EVO X in the works.

Eagle Talon here, so sort of a little bit.

Although technicly not DSMs, EVOs are DSMs at heart. So if it will be allowed, the inverse could be true. So at heart, your DSM can be EVO (maybe with a 1 over it err something).

As for me, I drive an 04 EVORS daily (had an 1998 EclipseGSX for 3-4yrs).

I am look forward to the good that this forum may bring. (hoping it doesn't go the way of so many others).

I hope our project EVO gets Mitsubishi people interested. Its going to have starte of the art chassis mods and hsould be a handling moinster.

chassis? I'm interested in the application of a certain engine manufacturer's ecu in the IX.

We are going to run Moton 3 way motorsport dampers. For the ECU in the bolt on stage we are going to use ECU flash. Once we get into the engine internaly and go bigger turbo we will do some sort of stand alone and go speed density. We are leaning toward motec since its plug and play.

What sort of ECU did you have in mind?

one that does a bit of logging on its own, talks with the lap top later, and uses toolbox to sort the data.

anyway...

I look forward to seeing your Moton build. Be nice to your res. lines ;-)

If you're looking to save any kind of money, the people at EvoM have just cracked out a speed density patch for the stock ecu. I believe it's only out for one ROM image, but that'll change quickly.

I think it'd be cool to see exactly how far you could go with the stock ECU.

I think thats sorta old news but it never worked all that well. This is the hack that Bez cooked up right? As I recall it had part throttle driveabilty issues.

If this is something new, can you post up the link?

This is the most recent thread I found. I just glanced over the first post and he said he was pretty issue free.

Wow thanks! More things to experiment with. Bez had tried it a couple of years ago but never fully got it running right and I havent been on EVO M since I got really busy.

EVO X owner here! Very excited for both the Evo IX and Evo X projects!

Great thread. I have an Evo X

The stock ECU is as good as any stand alone. The stock ECU has protection parameters in it that the motec does not have. Mellon tuning has now put more than 700 hp using the stock ECU. You can use the stock MAF system up to 500 hp. There are speed density patches from JCSbanks on Evom, as was mentioned. You can store up to two maps in one ECU and switch between them. I have tuned meth/water and E85 on one map and 91 octane on another map. They work as advertised. There is absolutely no reason to go the stand alone route when the stock ECU can get the job done as effeciently and with more protection to the engine.

Did you do a speed density conversion yet? I need to hook up with you, boost leak fixed.

Eh... i'd argue against the stock ecu being as 'efficient'. The capability of a proper stand alone is vast. As with anything, when you start getting near the limits of anything, the cost of incremental improvements goes up exponentially.

To take advantage of the capabilities of stand alones, you also need a ton of money dumped into instrumentation. I haven't seen that sort of commitment in any of the US time attack cars.

I was at a drag race event this past weekend and was hanging out with a team from Florida. Now these were some 'good ole boys', straight out of the country side. I'm not sure you west coast boys would understand what they were saying But damn if their car didn't have a ton of instrumentation on it! Every cylinder was instrumented with EGTs, turbine inlet pressure, pressure transducers everywhere. They showed me some of their data including boost. Their crew chief was telling me he can make the boost curve do whatever he wanted based on speed, gear, rpm, distance, whatever.

Check out some pro race vehicles, and they have things like LVDTs (linear varible distance transducers) on the shocks, laser ride height sensors at the four corners of the car, etc. Heck, I saw a pic of a MotoGP bike with a transducer on the shift linkage.

Modern MotoGP bikes have gyros and stuff to detect lean angle of the bike. Based on lean angle, the ecu can adjust the traction control and throttle input settings. Just because the rider 'asks' for a certain amount of throttle doesn't mean he's actually getting it. The ecu can set a max limit of throttle angle based on whatever inputs, regardless of what the rider wants. The engineers in the pits are essential to the rider due to the vast electronics built into the motorcycles and all the controls built in.

Anyways... the stock ecu can get you 90% there, but you need more capability to get that last 10%

With all due respect to nj1226 (who composed one of the best threads ever on "How To Tune An Evo"), for some of us there is much, much more to an ECU application then just HP, MAF two maps, basic engine management and patches that may or may not work. One point of reference, Pectel SQ6

To spdracerut;
I’m not sure how much you follow US time attack cars but I hope you continue to research your remark “I haven't seen that sort of commitment in any of the US time attack cars” further. If you need some help doing this, check out the Unlimited class in the Redline Time Attack series. You may think twice before making that statement again.

Also, please be respectful when you talk about “I'm not sure you west coast boys would understand what they were saying” We’re very sensitive to the suggestion that we don’t understand”

I havent seen much data logging on the suspension side of things in Time Attack cars although yours might have it.

Well, I'll say that the US cars have definitely stepped up their game this year compared to years past. And I take it the SSE boys will cause the competition to elevate some more. I see Time Attack as a relatively amatuer level of motorsports with regards to the sponsorship level. So a lot of teams paying for things out of pocket and with relatively limited sponsorship. And of course, limited funds means limited instrumentation and testing.

So top level would be F1, Nascrap, Indy, etc in terms of sponsorship. Koni GrandAm/Speed Worldchallenge probably get the next most money. I'd venture to guess that D1 Drifting gets a fair amount and they should as it's an actual 'series'. I'm hoping to see Time Attack gain more exposure and be able to bring in more money. At which point, I'd expect the cars to really elevate.

With regards to the west coast/east coast, man, I grew up in the South and still had a hard time understanding what those guys were saying!

I think NJ was assumng this project is a dual duty/street/track car, in which case a Pectel ECU is overkill and the factory ECU is probably quite suitable.

I think the comment about not understanding meant that their accent/manner of speaking might give west coasters trouble to understand and not that the subject they were talking about would be to complicated or advanced for west coasters to understand.
