BTW, the DIS v/s Distributor triggering issue is not a problem, read Shannen Durphey's post that Steve Ravet forwarded to the list on Feb.23 this year. With that posting and help from Bruce Plecan, I'm running DIS on a 1982 I6 BMW engine with $8D code (from a V8 'vette, originally with distributor). -- Tomas J. Sokorai Sch.

Hey Ryan, I know you're on thirdgen also so you probably already know about this, but those guys designed one some time ago and the plans may still be available.

Why does the 749 have 2 pins for one bank and 1 for the other!? I only need to run 4 high impedance injectors, so plan to just use one ECM pin for the -ve side of all the injectors, and another ECM pin for the ground connection. I'm trying to be sure which pins to use on a 727 when running $58 code. :-) BTW: Should the ECM pin to ground connect to the battery -ve terminal or the engine?

The newbie with the 4-Cyl 151 Iron Duke and the CJ7? Well anyway, I'm finally able to start working on my Heep again... and am curious as to how to set the timing on this thing... Now, all vehicles have some sort of timing advance... on carburated engines (just spilling out how I understand it... correct me if I'm wrong with anything) you unplug the vacuum advance hose and plug the port as to not cause any vacuum leaks... and set the timing... on a TBI'ed vehicle... there is a special wire that has an in-line coupler that allows you do disconnect the signal sent to the Distributor for the electronic advance... unplug that, set timing.. yadda yadda But here's my problem: On a 88 Chevy S-10 Pickup, "there is a black/red wire under the passenger's side floorboard that you can disconnect and then set the timing"... well... I obviously do NOT have an S-10... nor any wires inside of the firewall as I just spliced most of the wires off that went to the fusebox... and I've followed diagrams of the ECU pins and could not find any mention of this special wire... However... on GM-ECM I found a schematic for the 7747 ECM (ftp://ftp.diy-efi.org/pub/gmecm/manuals/1227747/747ecm6.jpg) -which is NOT the ECM I have... (if this information is current, got this from an old post I made a while back on a different forum:) mine is: SVC# 16198445 Barcode: 866647W643273117 Chip Inside: ACKD 4890 The previous link to the 7747 indicates the TAN/BLK wire right off the distributor controls the timing bypass... now I've disassembled my wonderfuly sexy wiring loom and traced all 4 wires that come off of the distributor...and each one of them goes DIRECTLY into the ECM... none have any splices in them as well or any disconnects in-line... Would splicing into the wire, and creating my own quick connect/disconnect in-line plug right at the 4-pin connector off the distributor be a good way to do this or am I missing something? I could simply "just try it" but I wanted to run this by you all first... you guys seem to know more about this stuff than any of us on JeepForum Thanks again... !! By the way... the Jeep runs... haven't started it up in 2 months and it fired right up... however it idles a bit rough and doesn't have very much power at all... so I figured timing would be the issue! I previously set the timing by luck by putting it at top dead center... unplugging the whole entire 4 pin connector off of the distributor -which doesn't allow the engine to run- and had a helper eyeball it to 0* and plugged it back in... Anyway, enough length on this... any other questions or things I should look at let me know!

Vertical position, board mounted? What terminal block? C&K SPST switches are $3.00 min. Sure LED's, 555's, and resistors are cheap, even at Rat Shack's inflated prices, it is everything else that costs a bit. Hell, some of the instrumentation amplifiers I buy (INA101AM) run $25 each. Whats your time to develop a circuit and layout? You can get board costs down to ~$25 each provided your willing to spend $500 bucks and order 25 boards. Set up fees alone are over $200.

I found out late about the ECM test bench boards made by Saturn5 and got one of the few left from the first run.. Built it using the spec parts and it works great, upgraded some switches to locking lever ones to prevent accidental turn offs, I'm not even using it on the ECM it was designed for, and I'm using it it with a dual coil pack/ignition module setup. I have a dedicated PC with Freescan and tuner pro wired up with an ERPOM emulator right next to the o'scope.. This emulator is one the best bench tools I've ever used for tuning/code changes Works great... So great in fact that when a second run of boards was done I purchased another one, it's now mounted into a pelican case with connectors for the ECM and some switches to swap between the board generated signals, and actual sensors. (I do track support and engine tuning for a race team, comes in handy to test sensors and calibration changes) This along with a IBM T-20 laptop an EPROM burner, and a solid state logger bolted into the race car connected to the ALDL stream has made my tuning at the track or on a dyno a breeze... Logical and neat terminal connections, fused power, clean design... Cross talk on the RPM and VSS?? I haven't seen it... and I've done a ton of stuff with interfacing different VSS sensors and playing with the RPM signals to deal with the dual coil ignition pack. There is a difference between "inexpensive" and "cheap" Personally I think the original was inexpensive, and was worth the money... Could it be made "cheaper"? perhaps.. If another one was offered. would I buy it? possibly.. since I'd like to dedicate another one for an upcoming project.. If saturn5 made more of the his original boards.. I buy two more... in a heart beat.. or perhaps with saturn5's permission he would let me do a run of boards for myself.....

This is why it's important to shop around before having a board laid out. 10k pots - digikey part #CT2265-ND - $1.51 12 position terminal block - DK #27-1587-ND - $1.97 $3 for SPST switches is ludicrous. Just a quick search found these board mount ones for $0.73 (#SW148-ND). When you're buying between 4 and 10 of these various parts, every dollar you save really starts to add up. I'm guessing you were spending close to $5-6 for those terminal blocks? maybe $3 for pots? I can see how you got to $75 in parts. I can get a circuit and layout done in a week or two. I hear you about the people disappearing. I've lived through that with some other things I've sold. Everyone's interested until it's time to pay up. Ryan rawardsr at ameritech.net wrote: Really?

Sure LED's, 555's, and resistors are cheap, even at Rat Shack's inflated prices, it is everything else that costs a bit. Hell, some of the instrumentation amplifiers I buy (INA101AM) run $25 each.

Are you running two of the Holley 4BBL TBI's or something else. I ran a similar setup on a 500HP 383 stroker using a single 900 cfm Holley 4BBL TBI on a 16197427 PCM. I built quad P/H injector driver box to go between the TBI and PCM. No reason you could'nt use two boxes and run two 4BBL TBI's. HotRod never gives credit to the people who push the factory EFI to the limits. It does'nt sell their advertisers parts. Tom Programmer wrote: Just a heads up for you guys...

So if you have a value at 400 and a 50% increase in the value at 800, the ECM would roughly assign a value of 25% more than the value at 400 and 25% less than the value at 800 for the value at 600 since 600 is half way between 400 and 800. I hope I have not confused you further, just think of the tables as a whole and don't break it down further than the cell. Mark BTW, this is my first post; I have been subscribed here for about a week but have spent a long time on many other forums and mailing lists. I gathered a wealth of information from the GMECM site when I dove into DIY tuning. -----Original Message----- From: gmecm-bounces at diy-efi.org [mailto:gmecm-bounces at diy-efi.org] On Behalf Of matthew10_5 at netzero.net Sent: Tuesday, August 08, 2006 10:31 PM To: gmecm at diy-efi.org Subject: [Gmecm] Editing Cell Tables I am using TUNER PRO to edit my VE Tables.

Maybe someone would be kind enough to unshroud this for me...Thanks..Matt From Robin at FuryWorld.fsnet.co.uk Wed Aug 9 00:02:22 2006 From: Robin at FuryWorld.fsnet.co.uk (Robin Handley) Date: Wed, 9 Aug 2006 06:02:22 +0100 Subject: [Gmecm] Editing Cell Tables References: <20060808.203116.4252.637759@webmail49.lax.untd.com> Message-ID: <00d101c6bb71$014f2360$020101c0@gandalf> I am using TUNER PRO to edit my VE Tables.

I think I may have just gone stupid looking at these. Maybe someone would be kind enough to unshroud this for me...Thanks..Matt I don't use Tuner Pro, but it should exactly reproduce the lookup tables in the calibration, as there is no reason for it to do otherwise. There is a lot of on-line information about the 747 - to indicate what is in the calibration. If the VE table shows 75% at an RPM of 400 and a MAP of 90 then, if the RPM is exactly 400 and the MAP is exactly 90, the table lookup code will return (output) exactly 75%. However, very rarely will RPM and MAP (input) values match exactly with the tabulated values, so the code does bi-linear interpolation between the tabulated values straddling the input values to calculate a sensible value for VE under those input conditions. This ensures a smooth and continuous transition between one set of input conditions and the next.

I must be doing something wrong. I am trying to burn an ANLU .bin in a 2732 chip for a 1228746. I have a Willem programmer, and a blank 2732 and a blank 27C32. The Willem programmer is able to read 2732 chips without problems. To test it, I read an ANTT chip (F-body 305 TBI), and it read without problems, and the data in the resulting .bin file made perfect sense in TunerCat. So I start with a 2732 chip that I know is blank, put it in the ZIF socket in the programmer, select 2732 in the software, and set the DIP switches as the program shows. I click "Burn," and it says it is burning, but when it gets to the "Verify" step, it shows an error at the very first address. I read the chip, and nothing has changed. Every bit is still a 1, so it is still blank. The programmer interfaces with the PC with a parallel cable and I have the USB cable hooked up to provide 5V power. What am I missing? I get the same results whether I try the 2732 or 27C32. The markings on the two chips are as follows: AM2732 ADC 8318DP C1983 AMD B8652 NMC27C32Q -45 Any advice would be most appreciated. ---> Jared Ryan <--- jryan at caminofx.org | http://www.caminofx.org From Robin at FuryWorld.fsnet.co.uk Thu Aug 10 02:27:03 2006 From: Robin at FuryWorld.fsnet.co.uk (Robin Handley) Date: Thu, 10 Aug 2006 08:27:03 +0100 Subject: [Gmecm] Burning 2732 References: <10a1b41367ad62635c0506f859b86127@caminofx.org> Message-ID: <012e01c6bc4f$322bfe20$020101c0@gandalf> Has your programmer ever successfully programmed an EPROM?

I discovered the Willem forum, on the willem.org Web site, and found some threads where people were discussing exactly the same issue, with the 2732 chip. It turns out, after I switched the positions of the jumpers at JP5 and JP6, the chip burned properly. Apparently this chip needs much higher voltage than most to program. I have not put the chip in the car yet (will do so tomorrow), but the chip verifies perfectly against the .bin file, so I am hopeful that it will work well in the ECM. This is the first EPROM I have ever programmed, so I hope it works. It is an unmodified .bin for a 1989 9C1 Caprice, which should be a close match to my engine to start with.
