Just to be clear, as you have mentioned a couple solutions for the stalling with factory programming in MT converted cars, will the new software still drop fuel and timing to zero when decelerating with the auto, just as stock programming does? Does this programming benefit fuel economy?

Then, the MT guys will wire the ECU to N, to be covered in another thread? If the MT guys can get around this, and the autobox guys can get all the economy available off throttle, that's perfect.

That is correct. The stage 1 software still has the fuel cut on decell just like factory.

Then the mt guys will wire the ECU to N to deactivate the fuel cut on their cars. If that doesn't work I will make them a 2nd version specifically for manual transmissions. I am not removing the fuel cut from the standard software for automatic SVXii.

Quick question, wont wiring the ECU to see nutral all the time disable the cruise control? I thought that was why we set the car up to see nutral when the clutch was pushed in. That way the cruise control could be used and it would shut off if you pressed the clutch in. I've also learned to not push the cltch in until the engine is below 2000rpms when stopping. That seems to prevent the stall, because the engine is under load still while stopping.

I'm not sure but you may well be right. I wasn't thinking of that. I'll have the test bunny pay attention to that too. If that is the case then I will make a seperate version for cars with manual transmissions. When I am in front of the factory service manual I will pay attention to if the signal to the cruise control computer is actually coming from the ecu or if it was originally just on the same circuit. If they are just on the same circuit we can wire them seperately so that the ecu always thinks it's in N but the cruise control only thinks it's in N when the clutch is pushed in. Even if the cruise control computer is getting its signal from the ecu if its just a high/low switch we can wire it seperately.

Well...wouldn't wiring the clutch peddle up to show neutral when you press in the clutch peddle FIX the stall problem?
As the ECU would see it as being in neutral (when coasting with the clutch de-pressed) so it wouldn't cut the fuel?

That is how I wired mine, and I never had a stall problem...so maybe that's why....I only wired it that way to make the cruise control work....

Just some thoughts...

Yes, you would just have to continue holding the clutch in until after you stopped.

this manual transmisison stuff is quickly starting to dominate the stage1v5 thread. There's no point in talking about it in here. I won't really be ready to talk about it until I can sit in front of the schematics and actually know what I'm talking about....I'll start a new thread then to discuss it and see if we can come to consensus on if I should make a seperate version specifically for manual transmissions.

Anyone who has an older stage 1 and didn't get an email from me isn't on my list of registered owners or I have the wrong email for you. If you want to get update notices like this and be eligable for upgrade pricing send me an email with your serial # email addy and shipping address.

how about folks who purchased the stage 1 and upgraded to the stage 2 and then bought another SVX that could use the new stage 1

I would have left you out of the emailing assuming that your stage 1 was replaced with the stage 2.

Uh, oh,
Just installed it and now I have a check engine light.

Codes 37, and 55
37 may be because I'm running my A/F gauge from that ecu lead, but 55?
Why would it throw a 55??

Why is nothing ever easy on this car...
