Nice. I hope they get the firmware for the VQ30 hammered out soon and that it works for us. If it does, I'll be getting the EU without question, even if the rev limiter increase never works.

Being able to come off the line under boost > not coming off the line in boost.

 

Nice.
On slicks I launch at 7200rpm with a 75 shot and have no problems.

 

I'm planning on connecting it to my 4 wheel line-lock vs the speed sensor so I can manually control it when I launch, that way it will release before the car moves.

I'm not sure how much movement it will take or what speed must be achieved before release on the EU. I guess it depends on the speed sensor and EU setting if it has the ability to do that or if its just the RPM that can be changed.

 

You're nuts

 

Thanks for the news Neal. I haven't been around for a couple days so hadn't seen that yet.

I knew Brandon over at Transonic had this working on his IS300 months ago, but I don't think it'll work for us without the crank input. I have tried it on my car using coil inputs but to no avail. At least when we do get functionality, it'll be easier than for the Z guys, our VSS line comes right into the ECU, I already have mine hooked up to the EU. On another note, I still can't believe no one over on the Z board has tried to increase the rev limit. It'd be the first thing I'd do. Bunch of scaredy cats... hah

Jim: nice sig pic! If you were using the speed sensor you can tell the EU how many pulses it should see before disengaging the set rev limit.

 

Dan would this work to modify the speed sensor signal or rev sensor? Digital Pulse Adjuster or Speedo Adjuster.

Basic Description:
Called the Digital Pulse Adjuster (AUD$79.95), it works in much the same way as the Digital Fuel Adjuster but instead of being able to intercept and remap voltage levels, it does the same for duty cycles. It is also different in that it can directly drive the output, for example a solenoid valve. Uses? Well, anywhere you have a pulse width modulated solenoid in action (variable weight power steering, auto trans lines pressure control, factory boost solenoid, extra injector), the response curve can be remapped.

I'm trying to find a way to change the shift points for my auto. The speed sensor seems to be the key but of course its a pulse signal and can't easily be modified unless you know an easier way?

I have the full article on it from Autospeed Magazine if you are interested in reading it.

I launched at just 4500 last year on a S/C and my clutch tore itself a new one!

How the HECK does soemone juice out of the hole at 7200RPM and not just KILL his tranny!?

 

Built trans...

 

Jim I took a quick look... I think the DPA looks promising. There's no signal shown in the 95 FSM for the revolution sensor, but it does mention it's a pulse signal so it should likely work, especially since the PDA says it can do 0% duty all the way up to 100%.

From what I can gather, the shift point decisions seem to be made by the A/T control unit based on inputs from the inhibitor switch (ie which gear pos), vehicle speed and TP sensors. And it primarily uses the revolution sensor to calculate vehicle speed so that'd be the one to use I'd think. Looks like the VSS via the combo meter is only used as a back up if the rev sensor malfunctions. Hopefully it doesn't compare the 2 all the time as a check...

 

The problem isn't really launching at 7200 rpms. It's launching at 7200 rpms on fat 26-inch slicks with a 75 shot, a forged 3.5 and double digit boost.

 

I don't understand what your post was about but that's ok
