I am reliving my days of hexidecimal real reflash tuning working with raw code today tuning my first 3rd gen Eclipse

The car has a

Doug's dyno power turbo kit - great product
Maganflow 2.5" exhuast
walbro fuel pump
440 injectors
Forge MBC
Fuel regulator

Originally the car had a emanage

I was able to use the tacrix cables and extract the raw hex data and then I was able to use my old hex editing skills to retune the car

When it came it it was running mad iginition timing from 33 - 28 degrees under full boost and knocking like mad - thus pulling timing

I was able to find all the timing maps and put in a more boost happy timing profile thus reducing knock

Also - I was able to speed up the transition from closed to open loop and eliminate a 15 / 1 sppol up a/f to 3800 which was killing the low end power

We are at an impass now with huge boost leaks - I will report back later

For now I am super excited to enjoy the fun of decoding another hex rom file - this is a art which I have not been able to enjoy since the ecu flash came out with its pre defined map addresses

Those who have a 3rd gen with a turbo or not - I am able to flash tune these now on a custom basis

Al

 

it would have been great for the 3G guys if you made a def file available now that you know the table addresses.

 

Nice I would have definately come to you if I still had my 3g Eclipse. Some people really trashed the car and I can understand their feeling of the change but I liked it. Was a fun road car with the V6.

 

Anyone who understands how the Evo ecu works can disect this ecu in about a half hour or less - its basically very similar

Sadly - this car is a moras of boost leaks and we need to send out a fmic pipe to a welder in the am to have it repaired so there is no end to the mission today

 

This car is a convertable - red - and its super sexy

These cars have a huge potential

I really am starting to like this machine

Tomrrow I am going to crawl under it and see if the evo drivetrain will fit

 

SHUCKS!

Can you elaborate on why it was tuned so poorly via Emanage? Is the Emanage system just not able to tune that specific car accurately, or was it a bad tune done by another "tuner"?

I wonder because i have a friend with a turbo rsx-s that runs Emanage and i swear the car is slower now than it was stock; i know it had huge tuning issues as it has been re-tuned 5 times and still runs completely sh!tty... I'm wondering if Emanage is just not a capable unit...? I wouldn't be surprised if he had 15-1 AFR's and was pulling tons of timing also.

 

i agree

 

The base iginition timing on the 3rd gen is very agressive - this is due to the fact its a N/A car

Also - the a/f tables are overly lean in the area of peak boost

I am sure that these issues would have been massaged with the emanage - however the previous tuner had added in one degree of timing through the power band !

You can see that the flashed ignition timing is much smoother and the car made the same power with a much smoother dyno sheet and no doubt a much happier motor !

Not to mention the speeding up of the transition from closed to open loop which picked up nearly 30 whp down low

Basically - any time you can directly access the ecu rom you will get a superior result than a piggy back


The emanage is a great piggy back - however - its not a reflash

BTW - the previous tuner did a hack job - bottom line is that many people in this business dont have the skills or passion to invest the time needed to do a good job. I have nearly 8 hours in this car today and we still have more boost leaks to fix and a watsgate actuator to re-adjust in the am and another few hours of tuning and data loggingf till its finished.

if the prior tuner had known to take a log of the timing he would have realized that the tuning he did was deadly

I will have some dyno sheets tomorrow I hope

 

damn, lots of stuff, gl

 

Al,

I wish you were around when I supercharged by 2000 Galant by www.rippmods.com . They were using a HKS afr at the time and the single from teh ecu to the afr was really crappy so I was never able to get a steady rpm reading. Now ripp is using a "black box" which is another piggy back system. You should be able to get a lot of business if you go over to the 3G forums. There are a lot of forced induction cars over there are that for the most part are all using the rippmods kit. my galant was the first galant they ever did, and i ended blowing three pistons because of that afr.

You should defintely check it out over there on their forums.

Good work

 

I don't see myself going onto the 3rd gen forums - that is unless I actually buy one to drive

I am sure they will hear word of what I am doing and a few may come by for a tune

At this juncture - All 3rd Gen tuning must be CUSTOM tuned only on the dyno - so my potential customers are those who live in my area.

Thanks AL

 

I had a 3rd gen eclipse. Sorry, but that car was built by monkeys. Also watch out for the pistons, they tend to crack if you look at them sideways.

 

Ok. Just trying to help

 

This thread may answer your question. I owned a 3g before my evo, and did alot of reading on that car. Your right it does have a huge potential, but not a huge market.

The pistons are the only weak point in the 3.0 V6.
Heads, Cams, Rods, and Crank are solid.
I made over 400 HP with my 2000 Eclipse GT and the only thing I had changed in the block was the pistons.

That was one car that needed to be AWD.
