The MSPNP suggestion box thread

sorry I didn't mention that it's been switched to OBD 1 with a '91 Accord distributor

That makes the job a lot easier. An OBD1 Honda MSPNP is likely to happen this year - sure, most Honda guys are going to be using Hondata or other hacks to the stock ECU, but there's still enough guys building Hondas that we should be able to capture enough of the market to make it worthwhile.

thanks... I'll wait .... what it has now is a local tuner with a program ( IIRC) called EC-Tune ... whatever ... it's "tuner locked" .. he's a good guy and a very good tuner ... but what happens if he moved on ?

so I was going to get a Hondata 300 and go from there .. but MSPNP sounds a lot easier

Are there any options for FC Mazda RX7s?

Not at the moment, but we'd definitely be interested if we could line up the right test car. (Check out this page for other possible MSPNPs that we could use a test mule for.)

I have a car that meets your criteria. But I'm in Massachusetts.

That could complicate things. Feel free to spread the word that we're looking for FC test cars on other forums, though - I'd post on RX7Club myself, but we're not a sponsor.

Will do

I think this is a huge gap in MS coverage. I know this isn't necessarily a MSPNP thing, but it's been bugging me so I'll continue on.

Electronic throttle pedals are used for nearly all modern powertrains, and none of them work without the factory ECU acting as a nanny (as far as I can tell). One could look at this a couple of ways...one is to use something similar to the GPIO to control a wide variety of different throttle body types and take the original controllers out of the loop entirely. I think that long term this will pay dividends, as it allows the cool new gee whiz engines to be used without major changes to the hardware, but this would be a huge project. Another way of looking at it is to recognize all of the great benefits that come with electronic throttle and figure out the most simple way to offer the same benefits on a generic sense...which is a little less daunting, I think. Not a one size fits all approach, but a single large throttle body/actuator can be used on a heck of a lot of different types of engines.

Many of the early setups had a throttle control module that monitored the pedal, told the ECU what the pedal was doing, listened to the ECU for instructions, told the throttle body what to do, reported any problems, and repeat...basically. It seems to me that rather than reinvent the wheel, it would be great if an existing control module, pedal, and throttle body that is common (such as GM stuff) could be used. The trick is in implementing software/hardware to mimic the ECU loop that would normally tell the control module what to do. Easier said than done, of course, but I think if MS is to keep up with modern powertrains, electronic throttle HAS to start being considered.

There really are a ton of benefits. Things like traction control, no-lift-shift, and even rev limiters get better. Packaging is easier. Engine bay is cleaner. Ditch the extra stuff for IAC. Basically, look to the OEMs, they've got lots of positive benefits from the shift. Not sure how your business could profit from this, specifically, but it's something I think has potential and from what I can tell is currently ignored.

What about a throttle cable box like that was on the 03 Dodge Rams with a 5.7?

We haven't been ignoring drive by wire, but it's got a much longer development cycle than new MSPNP models, which we can bang out pretty fast now that we have the Gen 2 architecture in place.

Matt,

Have you looked at a PNP for the Dodge Magnum engines? Either OBD2 or pre-OBD2?

The biggest thing holding back there is that Ma Mopar is very possessive of her ECU connectors. They're a bit harder to remove from junkyard ECUs as well. It's not an insurmountable obstacle, but would need a bit more money to overcome.

We could do it if someone on ProbeTalk or MX6.com organized an MSPNP On Demand and signed up 10 people willing to pre-order.

That's the life of a Mopar guy.

We're looking into junkyarding them - particularly since the Magnum engines and Viper motors used the same connector. And, in the case of pre-OBD2 cars, the turbo K cars as well. That just might give us enough volume to make it worth it.

I'll stay tuned.

Edit: No pun intended.
