Peak and hold injector driver board

Thanks for clearing that up.

Best confirm than guess and give others bad info.

Just need to find a decent supply of the IC's here and I guess the interest will increase a fair bit more.

Mario,

Fedex ground shipping would be $10 more than regular mail so $15 plus $18 per board. To your place it would be 6 days. For faster than that it's $40-$50.

Digikey now has over 2600 sense resistors (13FR100E-ND) available. I checked and all the other BOM items are also available in reasonable quantities.

TIP42 appears to be discontinued from my local parts place, given that I can get all else there, what can I sub instead?

Closest I found is a BDX34

racingmini_mtl · Post by **racingmini_mtl** » Mon Sep 04, 2006 2:48 pm

It should be fine. If you have a choice take the BDX34C which is rated at 100V.

EstateAgent · Post by **EstateAgent** » Wed Sep 06, 2006 2:51 am

Final double check - I've subbed:

The 4x 0.1ohm 3W sense resistors - I used the same spec, just with those concrete white brick ones

They are 2-3mm longer, so need to fit under the board.

TIP121's appear to be hard-to-get for my local supplier, so I subbed TIP122's
According to datasheets, they're the same - just 100v capable.

I think I quoted BDX34C as an order code, so i dread to see what actually appears

But i'm sure I got a TIP42 winging its way.

(I can get the parts elsewhere easily, but for minimum orders and surplus amounts, i'd rather just plug it and see

)

Be careful. You may not be able to fit the board in the last slot of the case if you fit the resistors under the board. It may not be an issue to have the board in the second slot in the top half of the case but I'm not certain that there won't be any interference with the MS board components because I haven't check. Also, the transistors would either need to be quite far from the board to use the case as the heat sink or use a separate heat sink.

No problem with that.

No problem here as it won't be housed in the MS case, rather in the casing MegaScott's EEC-IV adapter lives in (even that's a tight squeeze now!)
That way, I free-up 2 pins on the 37pin plug.

EDIT:

Just thinking; what was the issue/problem with using a counter (74 series?) using the/a cam sensor as a reset source, to make the injection sequential?

My engine (Zetec) has a cam sensor with a single notch, so every second crank revolution, the sensor picks up, presumably TDC of Cyl1 on Cyl1's injection stroke.

The counter takes its increment from the tach line and reset from the cam sensor. Wires into a buffer of some sort, enabling the right output, so the MS just fires as normal but is routed to the correct pin on your board.

I'll play in emulation, to see the best way i guess

Can anyone confirm that board works fine with new hi-res code? I'm about to load hi-res version in my MS1 V2.2 with 4 low-Z injectors and hope that p&h board will drive my injectors proper.

No one has one of these boards running yet,that can comment?

This board works superb I have been running it for a few week now with no problems .
Easy to assemble fits in the case great .
I will try to post pics here in the next few days.

I haven't tried with the hi-res code but there is no reason that it would not work. Since the hi-res code works with the standard injection driver circuit, it will work with the p&h board.

Will be trying high-res very soon with this board. All assembled - just got to put in the car yet.

Here is some pics of my install of the peak and hold board.
I am running fuel only on a buick V6 odd fire TBI injected MSV2.2 megatune 2.25 hr08g everything is running great!
Thanks to everyones help!
Note the extra wiring is from the old flyback board

71jeep,

Thanks for the pictures!

Did you have to change anything in your settings when going from the flyback board to the p&h board (opening time, VE, ...)? Or did you make other changes in your setup that make it difficult to say that the changes are due to the board?

By the way, I made a very basic web page with the basic information on the p&h board (http://www.jbperf.com/p&h_board/). Do you mind if I use your pics on that page?

Jean

Jean...

No i dont mind at all if you need more pics email me or PM me and will be happy to give you more sorry it took me so long to get them up here.
I just set my parameter as you suggested (which is setting it up as if I have high impedence injectors) and I was off and rolling .
I wish I could say if I seen a difference I had a problem with my install and I sorted it out as was installing your board and changing to high res code.So everything ran so much diferent when I changed code and after I figured out I had a bad distributer .
The one thing I really like about your board is I did not need to set the pwm parameters and worring about if they were right or not just put your board in set it and forget it

I would suggest this over the flybackboard easier to install and setup in my opinion.

hi, I've got few questions about replacement elements for this board. Unfortunetly I can't find few of elements by digikey number in my country.

Are this replacement parts correct?

DigiKey element / replacement
1. FR302DICT-ND / http://www.elfa.se/pdf/70/07010192.pdf
2. 13FR100E-ND / http://www.elfa.se/pdf/60/06002927.pdf
3. 39KEBK-ND / may I use 1/8 or 1/4W resistor - I can't find 1/6W

ps. sorry if something is obvious, but I'm my electronic knowledge is poor ;)
