NA is best - 3.1L M20 w/ ITB's

is there a dyno graph of this thing prior to switching to ITB/MS? its always interesting to see the gains

With the radio in the glovebox, curious to see what's in the cutout where it should reside. Gauges or stock radio?

Used to be a stock radio when it was all OEM, now it's... nothing. Just a factory blanking plate.

I can't wait to see what this will make when properly tuned! Keep it up

At last a warm enough Saturday to work on the car again!

Finally received new injectors after my first order fell through, after a month of waiting Paypal stepped in and refunded me on behalf of the MIA seller. Found and grabbed another set which shipped promptly and look pretty nice.



Next step was figuring out how to mount the MSPNP2 case. It's longer and narrower than the OEM unit and uses different generic mounting mounts. Made a template from cardboard of the two overlaid and cut an adapter plate from aluminum.







On to the next issue: because of the aforementioned difference in length, the control unit sat too close to the firewall/insulation and the DC9 cable wouldn't fit. Ended up ordering a 90 degree connector that did the trick and just made the squeeze possible.



Tore apart the center console and ran a vacuum line from the glovebox area through the firewall to the FPR, passed through the now vacant grommet behind the pedals that was previously for the cruise control cable.



Mounted and installed the control unit:



Reinstalled my radio and tucked everything in:

Great progress and build ! keep the updates up mate !

[MVincken]

nice progress! definitely one of my favorite builds at the moment!

Update?

Actually just received the Megasquirt today, excited to start reading and fiddling around with it. :)

After a lot of researching and looking around I ordered another set of injectors too, settled on a set of 24lb Bosch Gen 3's this time which I think should match my goals well. Unfortunately I have no idea when they'll arrive so I'll be waiting for that.



For now the car is back in my garage which is cold and dirty during winter. I may not make much progress until spring time... current plan is to prepare and do most of the remaining work on Easter long weekend.

yeah you have the right part for MS or any standalone, but not for the WAR chip is what i was trying to convey.

Oh wow right, that hadn't even occurred to me, I just grabbed the one suggested by RHD. Bosch # 0280122001.

That's normal potentiometer style tps and will work fine in alpha-n setup with megasquirt. Or alpha-n+speed densidy mode. The stock m20 tps is just thorttle switch as digger already suggested. It just tells to the stock m20 ecu if the car is at WOT or not. Nothing else. So the stock m20 "tps" is not good for itb setup.

thats a variable TPS right? different to the OEM part and might not be able to perform the same function

It has one jammed up near the firewall on the 5-6 throttle, hard to access but it's there.

Just ordered an MSPNP2 tonight. Decided if I'm going to have a go at learning and setting things up myself I don't want the headache of reading/writing countless times on the flaky old Miller software. The discussion between other standalones was definitely interesting, but I'm pretty sure this car won't see a more modern/advanced engine in the future and the MS support seems to be fairly user friendly for a tuning beginner like myself.

You Can't run WAR properly without the TS anyway right ? I've seen war used with RHD but it used a spacer to fit TS near thermostat housing

Ah, TPS was always my interpretation since "s" could be switch or sensor.

Motronic will run w/o the TPS, it will just never ignore the o2 like it's supposed to during WOT (probably how the MAF "works" with the WAR stuff).
