ECUflash Evoscan issue

[95Eclipse]

I finally installed Evoscan 2.7 "FULL final BETA" which I didn't see on their website. Not with that name anyways.
Well It does work on my 95 TSI. Sample rates SUCK though. I was expecting slow sample rates after reading from previous '95 owners, but this is awful, how can you use that to fine tune? and just in case you're wodering, yes I only selected like 4 items to log.
It only works when DSM/3000GT etc. selected. None of the actuators work, DTC's option seems to work.

I have a spare 97 GST Ecu, I swaped it just for testing before I uninstalled v2.6 and it worked great (except for DTC's option) and samples were very fast. The only problem is that I can't get the car to run right with this Ecu it "bogs" really bad arround 3K when under load. Plus It's giving me some other wierd problems as well.

It bogs because you have an inverted CAS. You'll have to swap some wiring in order to get the car to run right on the 97 ecu.

The reason that your 95 ecu has crappy sample rates and some things don't work is because evoscan can only connect through the obdII protocol which is very limited as far as transfer rates and basic usefulness. With the 2gb ecus 97-99 evoscan can connect over the MUTIII protocol which is Mitsubishi's own very useful very quick protocol.

If you have the opportunity I would really suggest attempting to pick up a 98/99 ecu as this will be reflashable and be more than worth the effort to swap.

Hey the_mork,
I had read about the sample speed/protocols issue, that's why I decided to try the 97 ECU I have.
I forgot to mention that my car has a 6 bolt engine, when I did the swap I followed the Magnus instructions and swapped my ignition cables as advised (well not the cables exactly, but the two coil trigger wires on the connector). I didn't do the injector trigger wiring fix on the ECU because they said the results were minor/subtle. Ever since the swap the car has been running "Ok" without that wring fix. I thought this 97 Ecu would work the same way.. But the difference is huge...
The only way I could get the car to idle and actually run w/97 ECU, was to swap he ignition cables arround untill it started, I guess if you have a stock 2g engine the ECU runs without swaping the ign. cables?

I do want to use this 97 Ecu for now, since I'm new to logging and don't have the extra ca$h. I want to get used to it before I attempt to buy/Flash 98-up Ecu, but I got a little confused with the instructions on swapping injec. cables.

From Magnus wesite:
Green: Pin 1 is now 14
Green w/ yellow stripe: Pin 2, is now Pin 1
Green w/ red stripe: Pin 15, is now Pin 2
Yellow w/ black stripe: Pin 14 is now Pin 15

Does this mean that since pin "1 is now 14" I would take the Green wire out of it's location on the connector and put it on the location where pin 14 is? or pull the wire from Pin 14 (yellow w/black) out of it's loc. and put it on the loc. where pin 1 is?
Does this make any sense?
any help is appreciated...

If you are running a 6-bolt swap with a 1997-99 ECU you don't need to swap any ignition or injector wires. Those directions only apply when you are using a 1995 ECU with a 6-bolt swap, or in a 1997-99 with stock CAS.

 

[the_mork]

95-96 are the only years that have a funky CAS therefore with the 97 ecu you should be running exactly the same way as the 6bolt originally came except to change the wiring so that you get crank and cam signals from the CAS (IIRC).

You'll only get around 8-10 samples/sec with the 95 ECU, yeah it sucks big time.

95's suck to log. When I did my 414hp dyno run, I hadn't really done much of any logging when I tuned it since the logging is so hopeless. I just set things the way I thought they should be, and then fine tuned the fuel map according to what my wideband said.

 

[95Eclipse]

This is great info,
I'm going to Re-install the 97 Ecu and give it a try, I will be swaping the 2 wires on the connector to the coil back to their original location.
Are there any downsides when ditching the Eprom Ecu, performance wise? Other than not being able to run DSMlink.
I am getting a code only when the 97 ecu is connected, P0105: Map/Baro. circuit malfunction, I do have the POT mod which helped me to get rid of the misfire check engine light on the 95 ECU, as you know this mod alters the value of the barometric pressure sensor. Am I also supossed to get rid of the potentiometer if I use the 97 Ecu?

 

[the_mork]

My (limited) experience is that you keep the pot, it may be contributing to your baro malfunction but it could also be the lack of MDP sensor in your current setup.

I got lost on that one.. What do you mean with my car not having a MDP sensor, isn't the MDP the same as the MDP/MAP sensor that's on top of the Intake Manifold?

 

[the_mork]

You have a 6bolt swap right? A 1g IM has no provision for an MDP therefore you've either left it sitting around in the engine bay or your MDP no longer exists.

 

[95Eclipse]

Oh Gotcha.. I did the 6 bolt swap but kept the 2g head, so I still have the stock MDP/MAP in place.
I guess the computter senses the diff on the baro. values and reports it as an error or something.

Do you or anyone else that reads this know the disadvantages of ditching the eprom ecu and keeping the 97 Ecu? if there are any

performance wise there shouldn't be any difference, as long as you have no plans on running ECMlink.

You can't tune. Pretty huge disadvantage unless you're staying stock.

 

[the_mork]

97 ecu offers faster logging and it might run a little bit happier because of the 6bolt you have in there. If you get the chance get a 98/99 plastic ecu, just start looking for them on ebay and in junkyards so that you might find one for cheap. You can also sell the eprom ecu for a fair amount of money if you don't plan on using it.

I was, but I have no cash right now, Maybe in the future. I'm keeeping the 95 eprom ecu just in case.

I'm sure I can still tune using MAFT or SAFCII, just not DSMlink since it takes a socketed Eprom ecu. right?

I'll be looking for a cheap one. I like the idea of being able to flash the Ecu using Evoscan. If you are able to flash the ecu (with evoscan) do you still need SAFC or MAFT at all?

 

[the_mork]

No, it is its own tuning solution so you don't need any other parts to tune the car unless you plan to change the way that the car meters or controls certain systems (such as switching to SD or adding a wideband). Remember that you will also need an openport 2.0 cable which is around $175 but still significantly less than link if you're worried about money. More than likely if you sell both of the ecus you have currently then you would have enough to purchase a cable and ecu with only a small amount of additional money. If you have an SAFC or other devices selling them will net you extra money as well.

 

[95Eclipse]

Great. I might stick to evoscan then. No I wish I had SAFC or any other way to tune, even though my 6 bolt has Wiseco pistons 8.3:1, still runs ok without a tune (not perfect of course, but it runs/pulls ok)
I'm going to see how the car responds to the 97 Ecu. I'll post back once I try it to let you guys how it holds up. I still need to learn how to read logs. If everything goes well I might get a 98 -Up ECU with the 2.0 cable.
One question though. Once an ECU is flashed can it be set back to stock settings? if so how do you save the stock settings, somewhere on the laptop?

 

[the_mork]

Yes, the process is easy. You usually start by reading the rom off of the stock ecu and then saving that somewhere. With the h8 ecus you then will probably use a rom modified by Ceddy along with his definitions to create a rom modified to your specific setup.

Reading logs and creating a basic tune is fairly easy. A comprehensive and perfect tune requires a fair amount of experience and time but a tune that makes the car fast and safe/reliable isn't difficult. Of course users here on the forums are always very helpful if you provide all the necessary information for them to help assess your tune so check back frequently if you are unsure of what to do next or how to improve on your tune.

Edit: FWIW evoscan isn't generally what you use to tune your car. It is a logging program. Ecuflash is a free program which can tune your car and the new beta of evoscan can edit and flash your timing and fuel maps but generally the work you do should be in ecuflash.

IMO SAFC's are a waste of money when there are awesome tuning solutions that you don't need to spend much money to do. EPROM (95 ECU) - burner or emulator and a cheapo logging cable; ECUFlash (98-99 & Evo ECU) - openport2.0 flashing/logging cable. Then get evoscan or one of the free loggers, and you're good to go. You'll spend just as much or more on an SAFCII, that can't do much. I had one, and sure it was fine for what it was, but selling it on ebay paid for a much better tuning solution.

 

[95Eclipse]

Yes, the guys here are always very helpful, by the way thanks alot for sticking arround and helping me out with my questions, much appreciated.
I haven't been able to install the 97 Ecu, I will tomorrow though. I hope everything goes as expected.

Do the H8 Ecus come from Evos? or what are H8 Ecus exactly? I've seen a lot of talk about that but can't figure what it means.. I figure something inside them makes them H8 right..
Also, I read somewhere that the ECU can only be flashed like 200 times anything true to that?

Yeah, that's the reason I'm trying Evoscan, I never liked the idea of having the SAFII device inside the car all the time, I wouldn't know where to decide to put it. Even though It would be great to adjust your tune on the go.

 

[the_mork]

H8 ecus are the plastic case ecus that came in 98/99 DSMs. No, there is little truth to the 200 flash limit. It is considered a manufacturer specification but is not a hard limit. AFAIK there have been several of these ecus flashed thousands of times and none of them have reached a flash limit or have failed for that reason.

 

[95Eclipse]

Thanks for clearing that up. A little bit after I posted the question I ran into ceddy's lair website which has more info about it too.

Well I changed the coil's wires back to stock position and Installed the 97 ECU, I'm still having the same problems. The car bogs when under load, mostly arround 2K RPM. it even feels like misfires/backfires. I still get the same DTC's as before too.
I wonder if it's got something to do with the fact that I'm running 8.3:1 pistons, but why wouldn't the 95 Ecu have that much of a problem with that? maybe all it needs it's just a good tune.

Again logging speed on 97ecu is like night and day compared to the 95 ecu.
