It's in the manual.

Re: Logic spark wiring
I just downloaded the pdf and looked thru the Web manual and didn't see the diagrams in the ignition section. Am I missing something? I may just be hungry and tired but I didn't see it anywhere.

Re: Logic spark wiring
Ok I found it in the base manual not the ms3x manual. I'm guessing the best way to go is not use the msx output and use the spark outs?

Re: Logic spark wiring
Section 5.3.1.3 Logic spark outputs - FET driver method, p. 76 for the description, schematic on the next.
Are you using a MS3 or MS2? Do you have the MS3X card?

Re: Logic spark wiring
Yes I have the ms3x been running it several years with pnp drivers. But I started with ms1 on this car and skipped Ms2. Tried the Ms2 but due to difference in trigger setup I didn't actually get running until ms3

Re: Logic spark wiring
Hi!
This thread has several options for circuits for the PNP booster, but I can't keep up with you
Can anyone please refer to at schematics that works, so I can order the right transistors? I run MS3X and want to use the vag coils. Planning to bulid a small external box to put the drivers inside.

Re: Logic spark wiring
Will the MS3X board be updated with the TC4427 elements ?
Re: Logic spark wiring
That's entirely up to B&G, the nice people who actually own the design, and sell the assembled cards to the various distributors. There are a number of "opportunities for improvement" that have been noted over the past few years, and it's due for a rev2.mega_user wrote:Will the MS3X board be updated with the TC4427 elements ?

Re: Logic spark wiring
Is it possible to drive a BIP 373 ignition driver through TC4427 chip?
MS3X uses a similar output chip for ignition outputs and can drive the BIP chips.

Re: Logic spark wiring
Yes, the TC outputs can be used to drive a BIP.

Re: Logic spark wiring
Does anybody build and sell a PNP driver "external box" ready to wire in? Kind of a Quadspark style.
I will be using MS3X and Audi COPs (NGK U5014).
Thanks,
Luis Roberto

Re: Logic spark wiring
Excuse my ignorance...
Why will a MS3Pro will drive the coils and not a MS3X? (both directly)

Re: Logic spark wiring
Thanks for the explanation.
The problem I have is that I already have the MS3X (with Mapdaddy and knock control).
So the alternative is via external box.. I can solder and follow wiring diagrams, but building a circuit...(as of now beyond my abilities).

Re: Logic spark wiring
Go with the TC4427. There really is no circuit building, just one 8-pin IC and two resistors per two channels. Take a look at section 5.3.1.3 of the MS3 manual; the actual diagram is on the following page.

Re: Logic spark wiring
Let me see:
I buy some stripboard, 15 ohms 1/4 resistors then

And then build this (attached image)
