Re: Need ECU recommendations please

Matt, just to confirm "A rapid RPM change while cranking can throw off the timing" (bolded): are you referring to timing being thrown off only while cranking (or momentary errors in timing), or continuing to be off after cranking and during running (sustained timing error during running)? Momentary...

Re: Need ECU recommendations please

So does MS always have to be tweaked and tuned or can you get a decent and stable tune Generally, once the tune is set, it stays set until you throw another round of mods on the engine. The cold start is something that you may have to wait for cold weather to dial in if for some reason the default ...

Ok, so I've got a vested interest in seeing you chose a MegaSquirt PNP here, but I'll give you a list of questions to help decide what is right for you. 1.

There are several ways to do this. Easiest way would be to remove the stock coil and power transistor, keep the distributor, and put one of these in it: http://www.diyautotune.com/tech_article ... _discs.htm

Re: ka24e ms2 v3.0

The signal wires run to the BIP373 spark outputs. See this link for wiring them up:

http://www.diyautotune.com/tech_article ... squirt.htm

You could bolt the second BIP373 to the endplate or the case lid.

Yes, and the center wire is usually 12V power.

This one needs external ignition modules or BIP373s to drive it.

There are different VW coils out there - I thought you meant the sort with built in ignitors.

They should work, but you may need to change the pull up resistors to 100 ohm.

Is this a solder cup or crimped connector?

They use a new method that ramps up how many cylinders have the spark cut, instead of cutting a fixed fraction of spark events.

It is really not a problem as your car takes two cycles to turn. I don't like working the starter too long to burn out. 10% of the time will turn on first bump, 40% 2nd bump and 90% 3 bumps. Rarely does it take more than 5 tries like 10%. I know it has to do with syncing of the wheel but I was hopi...
