Kamotors E30-Turbo to ITB M20

[kamotors]

ooor could it be the MAF?
i did a quick ebay search for M20 maf's but only AFM's came up. cause u had the Miller MAF there for the first start up I think. Now that the WAR chip doesnt have its MAF there its still running for its dimensions. email miller and send em your map and i think they will straighten it out
GL

its still using the Miller MAF sensor just a new housing(the correct housing for Miller tune) this is not the issue.
I have the correct injectors coming in any day to get the car running

Is your IAC still hooked up? I dont see it anywhere...

the ICV is hiding under the charge pipes.

Any motor work being done? If not your inspiring me already haha

What are your plans for gauges? Where are you going to place them?

What are your plans for gauges? Where are you going to place them?

I have the boost guage setup the same as my subaru and the wideband I havent decided on. I have a pretty neat VDO guage from the 80's that I got NIB. box was super yellowed and retro but the guage looks great. I dont have any pics but heres a pic to give an idea.It will make it easy so when I switch cars I dont look all over the place for gauges.

I need a little help wiring in my wide band I will be using it to simulate a narrow band signal.

My stock 02 pigtailasdasdasdasasd The innovate MTX-L

whiteasdasdasdasdasghghjghjdasdasdRed(switched 12v)
whiteasdasdasdasdasdasdaghghsdaisdBlack(ground)
blackasdasdasdasdasdasdasdghjjaisdWhite(headlight power)
greyasdasdasdasdasdasdhjkhasdasdYellow(analog 1 out 0v=7.35AFR)
asdasdasdasdashjkhjkhjkdasdasdasd Brown(analog 2 out 1.1v=14 AFR)

I'm confused... I've found write ups but non seem to have the same color wiring as me...

When I wired my m50 harness to my LC1 the colors were off as well. I used the pin numbers instead. Verifying the +12v and +signal with a multimeter so I didn't wire 12v to ground and melt shit.

Stock e30 o2
pin1 signal gnd
pin2 signal +
pin3 gnd
pin4 +12v

[kamotors]

ok cool that what I figured so I have

pin4-red 12v on wideband
pin 3 - black ground on wide band
pin1-??
pin 2-??

lol I'm such a noob to electrical stuff.

[kamotors]

so I think I got this...

pin4-red 12v on wideband
pin 3 - black ground on wide band
pin1-white
pin 2-brown narrow band signal

[brokenbimmer533]

I hear ya, I struggled with electrical work until I had a lot of practice with megasquirt on my build lol.
Not familiar with the MTX-L but the manual that comes with it says white wire need to be wired to headlight power? Seems odd.
The white wire on my LC1 is GND.

Other than that looks good.
I had analog 1 (yellow) go to the ecu (megasquirt in my case) and analog 2 (brown) go to my AFR gauge. Programming the outputs accordingly.

Not sure what the difference is between your wideband and mine (lc-1) but this is what I had.....

Analog 1 (yellow wire) as the narrowband. I have that hooked in to the stock o2 harness. That's the only thing I have in the harness. At first I used the 12v/ground/ground wires coming from the stock o2 harness but that didn't work. Readings were all messed up. So I used a switched 12v near the fuse box and grounded both wires to a bolt in the engine bay.

Make sure you have a good ground and a switched +12v, not a constant.

the wideband works and E30 runs:) haven't driven it but I still need to clean it up a bit. I'm happy:) turbo area is smoking a bit? guessing its just burning off any spilled oil and what not.

HOLY BUTT NUGGETS! I just drove my turbo E30 and it is WAAAAAY faster than I thought, it kills my subaru in 0-60. its hitting 6psi in first by 4k and it smokes the tires into second, I only made it 4 miles before my intercooler pipe blew off and I had to drive home N/A:(

also something is off with the AFR guage,when I let off the throttle it pegs at 22.4 but when driving around it fluctuates from 13-15after also occasionally it just reads HTR when stopped I'll go over the wiring tomorrow.

oh and not loosing boost between shifts is super cool

[Hey_You]

oh and not loosing boost between shifts is super cool

Anti-lag....or keeping your foot buried in the go pedal? Very clean engine bay I must say. I like it
