The MSPNP suggestion box thread

Got anything you'd like to see us build a MegaSquirt PNP system for plug and play tuning? If so, here's a thread to post it in!

ANYTHING CHRYSLER OBD2!!!!

BMW m70, Lexus 1UZ

Saturn S series.

Most of the boosted cars are already running MS, and I think a few have made harness adapters, but I would like to see a PNP solution. How many people do you usually want on a buy-in to develop a PNP setup?

We need 10 people on a buy in if we have the connector in stock. I don't believe we have the connectors for an S series. In that case, the buy in would depend on whether the connector was available and how much we'd have to shell out for an initial order.

BMW S54 standalone that works the dual variable cams in sequential firing and uses the stock sensors (additional AF wideband assumed) and harness but loses the integration with the rest of the car. It would be perfect if one could get a junkyard motor with harness, swap ECU and work from there as a running platform.

This would be highly advantageous to a lot of racers who will be swapping these motors in to BMWCCA, and NASA cars like crazy now that they have been shown to dominate this season. Current solutions are $3000 for the ECU.

If this is feasible for your team - I would try to promote 10 sales to meet the requirement but need to know if the MS3 is capable before going off on a funding drive.

This one has the same issue with Saturns in that we don't currently have the connector, but I know where to get them. It would need a cable operated throttle swap as well (or we'd need to engineer a drive by wire module - not an insurmountable obstacle, but it would add cost).

The dual VANOS part, though, would not be an issue for an MS3 based unit. The current MSPNPs are MS2 based, but we haven't ruled out MS3 based systems where appropriate.

RE: connector... if someone could send you 10 (or more) connectors pulled from stock ECUs... would that help? Saturns and their ECUs are super common in junkyards and not really high value, so it would be easy to do. I assume there is some hassle on your end as you are essentially starting with used components though. I don't have a clue where to look for a new connector.

Do you have connectors for the 1uz or the M70?

If they are available new, it's less work to buy them new and will make for a cheaper product. This is one reason the Ford PNP setups are a bit more expensive - we had to sort through junkyards and pick out the best connectors, then desolder them. It's a bit time consuming. If we can get the connectors new, we will.

That's OK. We do.

The biggest potential pitfall is that there's a ton of different Saturn designs, with incompatible pinouts and connectors. Each one would need a different group buy, and the current MSPNP architecture would only cover manual transmissions.

It looks as if we already could get the '91-'92 DOHC SL2/SC2 with a manual transmission - we seem to have the right connector already, although I will need to double check this. It may be best to see if we could do a MSPNP On Demand group buy for those first - we'd need 10 people since we have the connector. And depending on how that goes, we could look at later Saturns.

As far as I know, there is a 91-95 (OBD1), and 96-99 (OBD2) - that's all S-series, not just a particular body or engine. Different engines/transmissions may USE different pinouts, but the connector should be the same for those two sets of cars. Nobody cares about the 00-02 stuff anyway :)

Also, the harnesses are super easy to swap... I'd rather swap in an OBD1 harness to use with a MSPNP then create my own.

This might be helpful to you. https://www.saturnwiki.com/wiki/index.php?title=PCM_connectors

Damn, I think giant obrien purpelwhacker saw this thread coming.

SR20VE(T) NIssan motors are becoming quite popular as swap options in the Nissan/Infiniti crowd, that may be an area to look at.

In reply to MadScientistMatt:

I think that the 1991-94 1uz are that easiest to find. It would be going into something else anyway. The BMW would be a little different. I really don't see that one making it anywhere anyhow. The toyota though could be popular.

I've seen other sources - including Alldata and the ECUs pictured on RockAuto - show that the '91-'92 models have a black connector, while that link gives it as light blue. And GM connectors usually have different keys based on color. This is something we'd have to research further.

Anything Hyundai. C4 Corvette, non-LTx.

That year range covers three different connectors that I'm aware of. We don't currently have the connectors in stock for any of these, but we do know where to get them.

The biggest problem with M70 motors is that they used two ECUs from the factory. Might be possible to get them running with a pair of MSPNPs for a six cylinder BMW with the right connector - in fact, on the earliest ones with 55 pin ECUs, it may be worth trying a pair of the current BMW MSPNPs on them.

We could do a group buy for the Scoupe Turbo right now if anyone's interested. Some of the later Hyundai connectors are on the to-do list and they'd be eligible for a group buy when we have the connectors in.

C4 Corvette, non-LTx.

That's one we are looking into. We just came out with a Ford V8 MSPNP, so a Chevy one would make sense...

something for my CRX please ....

thank you

On the to-do list, but there's a couple things we need to make happen first. (For one thing, like the 5.0 Mustangs, it needs a different case design.)

Still waiting for a generic 4-bbl self-contained replacement...

That's going to take different hardware altogether. Got a few ideas on that one too, but it may be a while (either that, or we end up making a deal with someone who's selling off the shelf throttle bodies that we can resell at a good price... and that may take some R&D too to make sure they work as advertised).

In reply to MadScientistMatt:

I'd be a-ok with an off-the-shelf TB and your ECU, etc. I'll gladly be a test vehicle, too.

The MSD Atomic and FAST TB both look great, but the reviews/reports and pricing both have me scared.

'91 SI 1.6L .... you asking that question means that it might be doable ?? right ??? yes ???... hopehopehope

Right now we don't have the OBD0 connectors, but it would be pretty easy for us to make a replacement for the ubiquitous OBD1 "P28" ECU. And if we did that, add one of these adapter harnesses and you would be good to go. You could even keep the OBD0 distributor with a minor settings change instead of swapping in the OBD1 piece.
