a little T5 love

[Cm452]

Ok, I was misunderstanding what was said in all the reading I've done. The ECU does in fact have two different data storage methods, I thought it only had ram-but I guess that doesnt make sense now that I think about it as the car wouldnt "know" how to run after the battery went dead. I would guess that you are inclined towards the BDM? Seems that it is safer and in the long run cheaper, and less complicated.
This is fine, but soldering both an ECU and the motherboard on my LAPTOP scare me a little. Then there is the business of of running the BDM in DOS, which I am confused about, because I dont see how T5 Suite can "see" what is running in DOS, and how the two can cummincate through the DOS membrane if that makes any sense.
Again, sorry to protract this.

Is this the right ECU? It seems like it'll work-no? I'm looking for a low cost kinda thing.

Wish I could help you out with this...but I'm kinda in the same boat as you at this point

This is also especially tough when you consider the fact that Jzw can tune your car for about the same as it would cost to even *equip* yourself to properly tune the ECU, then there is always the chance that it doesnt work, and that you actually prove you have a very limited idea of what to actually do and as a result get a very poor tune and/or mess something up. BUT the whole idea of playing brain surgeon, ecu god, or whatever, is REALLY enticeing and cool!

I hear ya. I thought it was a bit cheaper to do T5suite though...I could be wrong. The way I wanted to do it is just do the generic stage 3 tune, but then as I learn more stuff, I would tweak it. But I'm beginning to lean towards the JZW route recently...I don't know what to do!

Hi,

You don't have to solder on the mainboard of you laptop mate. It is just the board in the ECU that needs a little header fitted. If you have a 1mm drill, a little sharp knife, a soldering iron and some solder (and the header pins of course, costing virtually nothing) you'll be done in about 30 minutes for a first timer.

Connect the BDM interface to the ECU Board and the other side of the interface to your computers parallel port. Boot in Win98 or DOS and start bd32.exe. All set.

The fact that you have to boot into DOS or win9x is because the freeware BDM software is dos based. T5Suite is just for editing the binary file (software from the flash chips) in this case. So, download the binary file from the ECU using BD32. Reboot in winxp (or whatever), start T5Suite and edit the binary file to e.g. stage 1 or so. Save the file and flash this altered binary file into the spare ECU that you have.

Does that make sense?

PS. Please DO read the T5 documentation which has all this described pretty much into detail.

[Cm452]

Yup, alright, thanks for clearing that up-someone who is more computer savvy than I said I need to solder it to my MoBo.
Alright, I'll look over the T5 documents closer, and more thoroughly this time, and if I run into any problems I know where to put 'em.
Thanks,
Cm

Yeah, he was right, I have no parallel port on my laptop, only a tin 15 pin thing for a screen, and whole bunch of USB drives.

In that case i'd say you have a couple of options:
1. Different computer with parallel port.
2. Buy pe-micro BDM interface that uses USB in stead of parallel port (expensive though)
3. Buy spare ECU and lawicel canusb interface and hope that you don't have bad luck and need BDM to rescue it after failing in programming it.

Ouch...I'll look into it,maybe I can find an old windows 98 machine.

I went to PE micro's site, they only had the BDM multi link-couldn't find the USB version on their website.
So basically, I'm SOL if I sink money into a CAN usb (really the only viable option) AND an ecu, and it turns out the ecu cant be flashed and/or I mess up somehow and I now I have a paper weight.
What are the chances that the CAN usb thing doesnt work-as in it "probably wont/will" or "Definitely wont/will"?
-Cm

[Dilemma]

Canusb will work in 95% of the cases if you set it up right

[Cm452]

Alright, I'll get myself a CAN usb and an ECU, and try it from there

[Cm452]

Will this work for the BDM? http://www.google.com/products?q=par...N&hl=en&tab=wf

-Cm

[Dilemma]

Nope. What will work is a PCI extension card for parallel port but i reckon you wanted to use this with a laptop right?

[Cm452]

Ok, I am now officially a member of ECUproject, and have read some stuff there from which I determined that I could only use a Factory Mobo Parallel port.
I'll go find a dinosaur and give it whirl!
Thanks,

I really need some insight into the transient maps on my Deka 630, T28 tune.

Specifically:
After start enrichment maps (Eftersta_fak and Eftersta_fak2)
- Acceleration enrichment maps (Accel_konst and Lacc_konst)
- Deceleration enleanment maps (Retard_konst and Lret_konst)
as well as the wot enrichment tab?

I reduced these all by 20%-in a lot of cases they won't go lower. I can't seem to attach the map here, but if anyone has any insight I'd be much obliged.
Thanks,
-Cm
