Who has a tuned ECU

[Edub1]

Who has a tuned ECU from a source other than JWT or Enthalpy?

Please specify E or DE motor, boost level and who tuned it.

Before I crashed I had a SOHC, Put a Zif socket in my ecu, got my self an eeprom and made all the tunes my self.

DOHCDaughterboard using twin ST flash M29F010B chips.

Original 370cc injector tune was done by deviousKA. I've since then reflashed for 520cc injectors and expanded the map for higher boost.

I'm runnin' 15psi on a T3/T04E.

KATwo40, are you in Houston by chance? I could use some help with my PLMS setup.

I'm in Knoxville, TN, but shoot me an email with your setup. Maybe I can help you out a bit.

KA24DECustom tune on PLMS board by myself.Boost level 12psi Map expanded for about 15psi.

Thanks, will do.

What boost level? Did you scale your TP values?

Calum board on it's way, using Calumsult. On it's way, plans to tune with it and emanage.

I'll be interested to see what you learn from it. Specifically if you observe changes in how the load scale is accessed. I'm guessing the load scale access will not change.

Not too many people have responded to this thread so far. I'm interested to see who has ran significant boost (>15lbs) with a self tuned ECU.

[Chezedik]

Well, I was following the Patent info thread, and I don't think there is anything too strange, but maybe I am still having a trouble understanding it. I will hopefully get my car running with it at least. I think emanage isn't enough to correct for 555cc injectors and a Z32 maf, since I am getting my plugs wet. We will see.

If there is more to learn, then we will see. Do you know if the Moates burner can be powered by just a USB? I haven't checked, I will do that now.

if you're in houston, go to houston240sx.com and send a pm to redss. he has done a number of tunes for our kat members.

I have the Moates burner - it runs soely from usb.

The thing about the patent is that it is just a patent for a method of fuel control that overcomes an issue of air flow not being linear with respect to throttle angle. It is not a patent of the whole ECU.

I was speaking to my friend who worked for Visteon as an embeded systems engineer in powertrain management and he was telling me that there are entire departments of Phds that design these ECUs. He was saying that a lot of them use numerous layers of maps as well as multidimentional maps to determine the end result.

I know a lot of people make big claims - I'd just like to see if anybody has actually ran big boost on a self tuned ECU.

I know that for the E motor, scaling TP by the same factor as one scales K is wrong, despite the fact that so many insist it is correct. I just wonder if anybody has actually verified timing with a gun or if it's just another assumption. Perhaps you will do a little experimenting.

[KATwo40]

I'll be doing it this week, Edub. The new datalogging setup should be here today or tomorrow. I'm currently runnin' 15psi, but I'll be doin' whatever it takes to max these STi injectors.

I'll post up results and all that crap.

BTW, I did scale the TP values in accordance with the K value reduction and the car runs like a champ. At first, I had some serious idle issues, but the injector lag was off. Changed it from 76ms to 72ms and the car drives like stock.

[Chezedik]

What size are those injectors? 570 or so? Can I see your bin?

[Edub1]

Trouble is, I have an E motor and can't adjust latency or expand maps or anything.

If you saw the end of that other post, you'll see that much of the data involved cancels out and simplifies to where the TP scale would actually represent a change in TP based on VE. In other words, the ECU via TP will boil things down to load/throttle position and pressure of course.

I'm just not sure if the E and the DE are the same. Also, I'd like to see actual end of the line output as these maps might be just part of a larger system.

Then again, there is always the possibility the E address file is not correct and that is why I had problems._______________________________________________________

Cheze, I'm working with an E motor. Not sure my bin would do you a bit of good. I can give you my K for 460cc, Z32 MAF it it will help.

[Chezedik]

I am thinking about KATwo40's.

[KATwo40]

Soon as I get finished dialing it in (should be today), I'll email you the bin. The STi injectors are rated at 520cc/min, but I can't remember at what fuel psi they tested them. So, we'll see how high they go.

BTW, 3rd gear, 4500rpm, WOT, 15psi + open diff = little bit of wheel hop....WOOOHOO!

[240sxOwner]

Is anyone running one of the ecu's from ebay...Redline Racing i believe, and today i saw a new one on there. Any experiance with them?

[Edub1]

You know, there is no reason we can't get a good knowledge base of tunes going. In fact, that gives me an idea for a new thread.

[Chezedik]

I would like to see a subforum for tuning, one that would move faster than ECCS.
