Babby's first MSnS

[beepee]

MS v3.0 PCB
MS-II cpu

Going from LH2.4 to MSnS.

So far:

- wired for VRIN and VROUT (not VRINV)
- have stuff to wire in BIP373.


1. Current limit circuit for driver FET protection (R37, R38) - necessary? Beneficial? Will be using low-z w/resistor pack
2. Active flyback clamp circuit - needed/beneficial with resistor pack?
3. PWM idle control - any special tips to use the bosch IAC?

I believe that I have all the components needed to make this thing go sans an IAT. I even have the TPS from a 960 TB - will this bolt on or will I need an adapter? Eventualy I will be using the 960 TB so it's not a big deal if it won't.

Jumper r37 and r38.

i thought the lh2.4 tps was right for ms to begin with.

cop or wasted spark?

dizzy for now - using the stock MS3 stuff for direct coil control

nay, just a switch.

3.1 tps/TB or 850 with adaptor!

Go wasted spark off the bat if you can.

Use miata coils and ignitor, it has a tacho output!

js10 or d14?

really? it's just one extra wire out for a second coil, and you can either get a second bip373 or run an external ignitor like dna suggested(what we did on hockey's car - if you've got the parts it's not any harder than the stock stuff)

 

[beepee]

i plan on doing wasted spark later - i did it and re-did it with MrBill's car so i'm familiar with the process. for now though, dizzy.

why pnp? keep it stock looking?

why pnp? keep it stock looking?

mostly cause I

1. have all the parts
2. don't want to redo the harness

shoulda called me, theres a much faster and easier way.

it took like 10 seconds to cut the connector off, and it was amazingly satisfying

ECU was dead anyway

yeah, i was gonna say, that looked therapeutic

Ok, wired up the PWM IAC per this page: http://www.msextra.com/doc/ms2extra/build_manual.htm

because I used the stock ignition driver location (which seems to conflict with the PWM IAC stuff) I wired the output of the TIP122 to the IAC1A output instead of the R43 location as suggested.

Now, DB37 -> LH2.4 time...

 

[WillettRun?]

just solder it up from the output pin on the db37 to the corresponding LH.

really?

this is tedious but after about 4 white russians you don't even notice!!!

It felt so liberating to finally clear out the last of the factory LH2.4 wiring from my car. There were always so many mysterious unused wires all over the place, under the hood, in the footwell.

I'm certainly still using some of the wiring. But all the unused stuff was either repurposed or removed. I should have taken a picture of the large pile of wiring that was left over.

Bought a DIYAutotune harness. Got tired of that ****e DB37.

it's not that tedious. there's a method. also, just noticed-you noobed it up on the board there, shoulda put the IC's to the right of the chip in sockets.
