ECUflash CeddyMod v1 (EcuFlash)

[Ceddy]

You don't hear many people complaining about their turbo spooling too fast.

BigMaps helps by giving you more resolution, the stock map has differences up to 8* between cells. You want smooth transitions, with small of change as possible between cells. Also with the stock map you will have the same timing anywhere above 180 Load, you have different needs at 180 and 300 Load.

You must be logged in to view this image or video.

So, BigMaps probably won't help you. Maybe a dual stage boost controller run on low when cruising could help.

My car is really hard to drive without spooling and pulling with the setup I have.
(3" no cat and fully ported FP E3B16G ported EvoIII 02, Large FMIC and EBC)

I can get 20-22psi @ 2800rpms. At 1/4 throttle I still start making 15psi @ 3000 and it just keeps trying to spool me up. Is it settings on the Profec? I have changed it to slow spool up down. If feels same on quicker and slower settings.

Like I have to shift it I can't just climb in RPM's (unless really slow and lightly).

I feel like I wish I had a regular car sometimes cause it gets annoying when I just wanna cruise but will the big maps help smooth that out?

I had a safc-II before and I don't know how the difference between AFC tune and a ECU tune will be for driveability can someone enlighten me? Or what I might want to do when I get to tuning the ECU w/ECUflash.

I know when I get my next turbo I won't be complaining bout quick spool up when I got a 60trim or more.

I used to feel the same way until recently when I switched to ecu based boost control. It isn't available yet on the H8 but I've seen Ceddy poking around the idea so it might be coming, encouraging his efforts is probably the best way to solve your problem.

Ceddy, are you getting anywhere with the ecu based boost control? I know there are some hurdles involved but you've tackled everything else with such grace that you're progress constantly amazes me. I'll never switch back from my evo8 ecu on this car because I'm happy with my current setup and rewiring would be a pain but on a future car I would love to run an H8 ecu with or without boost control. I was just curious because as mentioned boost control does make a car with a quick spooling but powerful turbo more streetable and gear dependent boost is wickedly nice. Of course I'm also just always interested in what is going on withing the community and with flashable ecus specifically.

Hey where in FL are you in Jeffo? I could really use some help with ECUflash when Im done in about a week or so and I pray I rebuilt the motor correctly I will need some tuning help. I have all proper equipment.

There are just some times I don't wanna spool up so quickly. I felt like with the afc I had to baby it throttle wise just to drive in the city. High ways are different but driving around NJ & NYC it gets annoying.

That and when I would let someone trying driving the car, or had my dad drive it the power it so hard for a newbie handle at only 20psi that the car jerks and its impossible to be smooth at.

I have PWM control of the BCS figured out, and killing all the stock BCS code frees up some space. And the Evo control system isn't as complex as I first thought. H8 Boost Control is doable, I just don't have a lot of time to test everything out by myself. The Evo coders have the advantage, that the day they release something they have like ten people testing their stuff and reporting bugs, etc.

 

[GSXeclipsePSI]

More people need to jump on this that have the ecu required.

As soon as I'm done I'll help the most I can its been a long time coming bout a year of downtime.

Maybe we can get something on the main page posting something like ECU FLASHING need beta testers.. For people who might have missed that this is all possible now.

 

[the_mork]

I am constantly surprised by how few people know about this and even a number of the ones that know what it is don't understand how powerful it is and still go with and MAFt or SAFC because they just don't see a stock ecu being able to offer them the tuning that they want.

It will come around though, I expect that over time you will see more and more users on this bandwagon and you'll start to see some competent testers.

Not sure if I've asked this yet, but since I've found some one to lend me a 2.0 cable I can start doing work with mine.

However, I'd really appreciate it if someone could send me a completely unmolested .xml for evoscan or at least one that has been modified for the DSM ecu specifically. I've messed with and tweaked with mine so much over the last year while playing with the Evo stuff that I don't want to risk something being off.

 

[jeff24680]

Ceddy, I am more then willing and capable to help you out with whatever specific needs you'd like, my profile is up to date.

I may not know how to read HEX and code it, but I am extremely capable at troubleshooting and problem solving. I don't know if my car has what your looking for but let me know if there is anything I can do. I recently fixed all my boost leaks my only problem now I believe is my ISC (I believe this because all coils were within 38-40 resistance instead of 32-35) is staying a little too open at idle giving me 15.7-16.0 AFR's at idle. Cruise, WOT, perfect AFR's, as the ISC has little to do at those speeds.

I am using all your mods right now except what I mentioned I turned off.

NLTS
Speed Density Look Up
Base Timing Terminal

If you'd like me to test something just let me know. Just got my new dual core netbook and in-car mount so I'm ready too GetRdonE!

Your evo xmls should be completely separate from your DSM xmls so no amount of messing around should have messed up your basic xmls that came with ecuflash.

Id be willing to help test this once I get my clutch and transfercase back in. I would also probably need some help with the initial setup if Hubbard or anyone near me would be willing to help seeing i have never used evo scan or anything like it.

I'd be more than willing to help you, but not until I get my car all setup and running well. I've done the Evo stuff, but haven't actually done any work with this ECU.

That would be great...I still have a couple weeks till my car is up and running....and the snow this morning here in illinois isnt going to help us much with tuning...Just let me know when your ready to tune...and ill let you know whats up on my side

 

[black_gst]

hey guys i just picked up a 96 talon and it has a 99 plastic case ecu and 99 engine harness in it... i have dsmlink in my 95 right now but i have done a bit of reading on the whole flash thing and im kind of intrested. can a flashed ecu handle 1600cc injectors? if you look at my mod list you can see what my mods are. i plan on swapping everything thats on my 95 gsx over to my Talon. and can i use the dsmlink cable to flash the 99 ecu?

thanks.

also i would be willing to test stuff out because if anything went south i could always swap in my dsmlink

 

[the_mork]

A flashed ecu can handle 1600cc injectors as well as just about anything out there. If you are using terrible injectors with stupid dead times you'll have some trouble with idle but no more so than with link.

If you are running e85 through those injectors it should be a walk in the park.

No you cannot use the dsmlink cable for flashing an H8 ecu, you will need to openport 2.0 cable.

The Evo coders have the advantage, that the day they release something they have like ten people testing their stuff and reporting bugs, etc.

To start with, a simple 2D RPM / BCS duty cycle table and another one for a subractor or divider based on coolant temp would be good enough. You could figure in throttle % with a DC% subtractor or divider for those that are trying to stay out of boost for gas mileage reasons. Another table based on IAT may be a nice feature too.

well the dead time is only 400 i think so not too bad i ironed out my idle with link but i am running 280's so she doesnt idle till she warms up a bit anyway and i have my FAIV completly blocked off as well

 

[the_mork]

I agree with jrohner that you can keep it quite simple. Error correction probably isn't even necessary. I know I've never bothered to turn it back on after I set my wastegate duty cycle.

 

[_Madman_]

I'd love to help, but my tranny got broken again few months back, and because of the financial crisis here all finance flows have stopped. It looks I'll be able to fix my car and get the OpenPort 2.0 only in spring

But the mods are incredible Ceddy! I don't know how you do it, but it's awesome what you have achieved!

 

[motomattxxx]

Any more progress with the inverted 2Ga cas signal? That one will be nice!

 

[jeffo]

Hey where in FL are you in Jeffo? I could really use some help with ECUflash

Sorry, I'm on the wrong coast. I'm down near West Palm Beach. I could really use someone in the area to test things out too.
I know what you mean about spooling too fast. I wanted my GVR-4 #1886 to have tons of lowend torque for good driveability, so I had a Cyclone, 264's, and ported EVO3 16G. The car always had an issue with bad compressor surge between shifts, because the boost would build way to fast and easy. The new owner has partially tamed it, but I think a bigger turbo may have been the only answer.

So how does the ground the timing terminal work? I flash it with it enabled and then I set my timing, then re flash without that option on?

 

[Ceddy]

No, it works just like the 1G and 95-96. You ground the Base Timing Terminal Pin and timing is locked to 5*.

You can leave it enabled, just ground it when you need it.

 

[GSXeclipsePSI]

All i can seem to find in my engine bay is a blue connector, not a brown one as the Chilton manual states.

 

[jeffo]

I believe only 1995/96 cars got the timing terminal. You need to add it to your harness.

 

[GSXeclipsePSI]

Ok thanks, I could just make a switch in my dash board area to just ground that out. So is there a pin for it at the ecu of do I have to make one? Ceddy do you still have pins left for sale?
