This WRX was picked up at an insurance auction and is likely to be used as an 818 kit car donor, but it got dropped off here along the way. It's not the most smashed car we've used for R&D, either.

Where's the smashed part? What I can see looks alright.

Smashed driver's rear corner according to FB....

The whole tail end - you can see a crease in the door.

Here's a picture with the full extent of the damage.

If the left front fender is OK I would like to buy it from you.

You guys need to do a newer Hy/Kia car.

We see requests on them occasionally. Would you be interested in organizing an MSPNP On Demand group buy? Short version is, we'd need 10 people to sign up for a single MSPNP model and put down a deposit:

We have access to a couple connectors not listed on the DIYPNP page; some of them might require a higher price or larger number of people in on the buy. You guys provide the market, and we can provide the ECU...

In reply to MadScientistMatt:

Interesting... any thoughts about doing a Bosch D-Jet replacement? Volvo 1800E/ES, 142E, Porsche 914, etc.

It wouldn't need to be a 100% PnP set-up as there's a fellow already selling a "stealth" system that re-uses most of the OE hardware, but it's pricey (~$3000). A more affordable option would be nice for those who don't care so much about keeping the appearance original and just want the car to run easily without having to occasionally source expensive NLA or rebuilt parts.

Ian - got a picture of the connector it uses? I don't see a reason we can't build such a thing, if we can get the OEM ECU connectors and demand is there.

To be honest, we wouldn't want to use the OE connector or wiring. For one, many of the problems with D-Jet are due to the 40+ year old harness. And while replacements are available, they aren't cheap (over $400). The connector at the ECU is a bit odd as well - it fits on to the end of a PCB. The main connectors to reuse - the injectors, CTS, CSV, & ATS - are standard 2-pin connectors still available. I'm not sure the other sensors (MPS, TPS and speed reference from the distr) could be reused, nor would reuse be desired (those are the expensive NLA bits).

I just dug out the harness from my disassembled car. I'll post some pics tomorrow.

Maybe I'm barking up the wrong tree... guys have tried selling pre-made MS harnesses for the B20 before in the Volvo world, but gave up after awhile. I understand the MS part isn't a big deal. It seems the biggest PITA is switching the speed reference from the distributor (which uses a mechanical points set-up) to something else - usually a TDC ring mounted on the crank pulley.

So what does the MS do better than the factory hack systems out there for Subies?

Features that the MS3 based MSPNP we're building for this car that I am not aware of hacks to stock systems supporting include:

  • Rally style anti-lag
  • The ability to run 2 stage injection
  • Timed boost and timing ramp-up after launch
  • Progressive nitrous control

The speed sensor could be used, or we could develop a crank trigger, but the biggest obstacle here would be cost. We don't have much experience building drop on harnesses, and I'm not sure if we could get the price under $400 or not. (Almost certainly wouldn't be able to hit that point if we made custom crank triggers.)
