Is anyone here able to email me the bin file for the 808 ecu so I can have a play around with it. Supposobly this is meant to be on the diy-efi ftp site but I cannot seem to get onto it.

the address you can send to is dj_slasher@hotmail.com

Thanks

 

I'm not sure what you mean by "the" bin file for an "808 ecu". There are a few '808 bins in the Binlibrary, but the best site is here and somewhat anonymous! Lots of descriptions of what the various bins were for and which ECM's they go in. I think it's the best list of bins I've seen for Delco's on the net (although there are other excellent sites with more info than just bins).

Are you looking for an .ECU for an 808 ECM, or are you looking for .bins (plural)?

John

 

I actually was sent Asbx5D and Aftx5D from someone on here, and I assume that these are for the V6 and V8. I am now after a suitable ecu file for the 808 that is suitable for winbin and also gmecmedit so I can play around with it.

diy-efi ftp site seems to be down too.

Also would it be possible to disable spark and use the use ecu just for fuel. I don't really need ignition control for the moment and I think that will just make the learning curve steeper.

The motor that I will be using this on will be an Holden 202 3.3lt.

So if you have any advice let me know.

Thanks in advance

 

Yes, you can run the ecm as just a fuel or timing computer.
It's best thou to have a complete and commented hac of the code so you can see any gotchas early on.
Thou, I'd suggest spending the time to run both with it.

 

The learning curve is not really any more difficult to get the spark sorted out with the fuel, and you'll at least have a better chance of getting the engine tuned properly. You also have to get a signal from something at rpm frequency to fire your injectors- you might as well get that from a Delco module, and you can adapt that to an electronic Holden 6 dizzy.

There is an '808 ECU on the ftp site that doesn't work because it has some formatting errors at the end of a couple of items- this is easy to fix with a non-formatting editor (Wordpad? I can't remember which one).

I'll email you a $5d ECU that works in GMECMEdit- that's the best program to work with for free.

John

 

Thanks JohnL, if you can send me the required ECU file then that would be great.

Do you think the stock V6 base map would be able to at least run my engine with very little changes? What settings do you think I'd have to change?

Also know any reasonably priced eprom burners available in australia that i could use to program the 808 rom? Is it a 2732?

 

I think you'll get the engine to run with the ASBX bin you've got, but only if you change the injector constant.

I don't know about a low cost eprom programmer. I built my own and had all sorts of dramas (runs fine now). Given the comments of others on this board, I'd buy a Pocket Programmer if I was doing it again.

The '808's I've seen have either 27128's or 27256's. You need to either offset or double up the bins if you burn them onto the latter.

John

 

Did you really mean ASBX because i'm pretty sure this is for the V8 and my engine is a 6cyl. Wouldnt AFTX from the V6 be better suited to my motor?

The injectors I currently have are bosch 0 280 150 203, they came from an VK EFI, would these be suitable for the 808 when i change the injector constant.

So you don't think i'll have any problems getting the engine running with the standard bin?

What about spark reference angle?

Just found http://www.futurlec.com/EPROMProg.shtml so this might be the way to go hopefully.

Also i've noticed some of the others ppl here are using adapter boards that mount into the ecu for the eprom, would i need one of these for the 808? These are the ones i'm talking about http://moates.net/gmecm/hardware.html

thanks in advance

 

Do a search here on Futurlec- I think you'll find people have had some problems. Try a search on Batronix as well.

Have a look here for 4, 6 and 8 cylinder ASBX's.

Bosch '203's flow 185 cc/min at 2.5 Bar (about 37 hp each). You'll have a pretty hot red motor if these aren't good enough

And yes, I think you'll easily get started like I said- it just may not run perfectly unless you luck in the VE's. That's easy to fix, it's your idle and transients that are more likely to give trouble.

The problem you'll have with modifying the injector constant is that you need to know what size cylinders and what flow rate injectors ASBX suits, so that you can proportion it for your configuration.

A Moates adaptor is a very nice thing to have, but you don't need it to get started. Have a look at Tim's Promintro article at the top of the stickies on this forum to see a memcal adaptor that allows you to program a memcal in the burner. You can buy a memcal used for about $25, so you might as well buy a few and burn those directly.

Work the spark reference angle out by setting the dizzy up to suit whatever is in the ASBX that gives the correct total advance. Search on this site some more and you'll get the idea.

Thanks for the help so far

Wust wondering if there is a list available of all the variables for the 808 that are included gmecmedit? I wouldnt have a clue what most of them mean. ie SPKct, SPKss, F60, 31 ---, 32 --- and basically most of the others, so if there is something out there that can explain these then that would be great. Also if there is any other info related to the 808 ecu then I wouldnt mind taking a read of that too.

I've also decided that i'll be using one of these to keep costs down. I'll use it to read and write to the eprom.

With limp home mode is that dependent on what memcal you use. Say if I use a camira 4cyl memcal on a 6 cylinder motor would limp home mode work?

Still not too sure about setting the injector contant, just doesnt make much sense to me

you said "The problem you'll have with modifying the injector constant is that you need to know what size cylinders and what flow rate injectors ASBX suits, so that you can proportion it for your configuration."

The Aftx5d.bin file i'm using is for the V6 3.8lt and the injector constant is set at 0.13 Grams/sec. So each cylinder is 633cc with the V6. My motor being 3.3lt, so each cylinder is 550cc.

Is there some formula to work out the injector contant based on those figures?

Thats about it so far.

Thanks in advance

 

1) Not that I know of. Search on "acronym", "parameter" and "abbreviation". The info is scattered all over the internet. Try downloading a copy of the turbop4.pdf from one of the sites. Ask questions about stuff that you're not clear on, after having done a search on it.

2) No. The netres needs the correct cylinder number built in. You can use a 4 memcal in a 6 (and vice versa) but if your ECM carks it, then no go, ie no run in limp home mode.

3) >> The Aftx5d.bin file i'm using is for the V6 3.8lt and the injector constant is set at 0.13 Grams/sec. So each cylinder is 633cc with the V6. My motor being 3.3lt, so each cylinder is 550cc."

You need the injector size that the V6 bin used. The IC, KINJFLOW, has units of L/gms per second, not just L. If your old IC is IC1, to calculate your new IC2,

IC2 = IC1*(L2/L1)* [(gm per sec)1 /(gm per sec 2)].

Find out what initial injector flow rate value is (or tell me what Bosch numbers on the injectors), then post your calc results and I'll tell you if you're right or not.

unfortunatly i didn't have much luck with the formula you posted. It didnt make sense too me, though I was never really all that good at maths.

I have worked out that my injectors flow 0.185 L/second. They have 0 280 150 203 stamped on them.

 

No they don't They flow 0.185 L/ minute.

You need to know how many L/s or L/min the injectors flowed that were in the V6 that had the .bin you want to use. Or you need to know the Bosch part number and I can probably tell you from that how much they flow.

If your maths is poor, do it this way:
* If the cylinder goes down in capacity by 10%, put the IC DOWN 10%.
* If the injector capacity goes down 10%, put the IC UP10%.

This will get you in the ball park.

John.

 

well that bin is from the V6 so all I need to do is find the part number of the injectors from any VN and that should be right? Or did VNs use different injectors in later versions? If thats the case then I have no chance.

I try and locate a part number for the VN injectors.

 

The VN came with 0-280-150-775 or 0 280 150 706 injectors.

Early VN 0-280-150-901 flow: 197.6 cc/min

Late VN 0-280-150-917 flow: unsure of flow rate

 

The 775's are blue top injectors IIRC- they flow the same as your 901's effectively according to my chart. The 706's are VN Group A injectors, and they flow 214 cc/min at 36psi.

Your 203's flow 185 cc/min at 36.3 psi. Let's say your ASBX is for a car with '901's. They flow 195 cc/min at 43.5 psi. To find the flow rate of the 203's at 43.5psi:

203 Flow @43.5 = 185*SQRT(43.5/36) = 203 cc/min.

If your old IC'901 was 0.13, IC'203=0.13*195/203 = 0.125

Now, your cylinder size has gone down by 3.3/3.8 (Cyl2/Cyl 1= 0.868).

So IC'203(3.3L) = 0.125*0.868 = 0.109

That's how it's done.

Thanks alot for that, so thats pretty much all I need to do to get my engine running. I'm going to see if I can pick up a camira ecu, wiring loom and all associated sensors soon so hopefully that should go well. I dont mind if the engine doesnt operate the best for the time being, just mainly want it to be running and drivable.

With the dissy, I assume I just have to lock it and block up the vacumn advance. Is there anything else I have to do? Any sites that can explain this to me better?

thanks
