Re: Inj Firing angle

"The Injector firing angle is the angle at which the injector will SHUT after the injection even has occured (relitive to a full camshaft revolution)" So the firing angle is relative to (before) TDC Exhaust? or Compression? I have the same question. I know you can program it to be whateve...

How to find injector dead time's from scratch...

Okay, I figured I'd post this. Matt from Haltech gave me this info. Credit for the idea/algorithm goes to Scott. :) Unfortunately its impossible for us to know all the details on all the injector types ever made by different manufacturers. There is a neat trick that Scott thought up for getting the ...

Re: Dead PS1000 box?

If the 5v supply has been connected to 0v or 12v for a prolonged period I would expect the regulater in the ECU to die Yeah, but all the wiring has been looked over and nothing has changed. This car ran fine for a while before this happened. Would that possibly 5v supply issue also cause the ECU to...

Re: Dead PS1000 box?

If all the sensors are reading flat out it would indicate that the 5v (orange) supply wire is shorted to 0v or 12v. Please check over the 5v wiring, as well as any 5v supplied sensor. Thanks for the reply Scott. The only problem there, is that I plugged this box into another running car, wired up w...

Dead PS1000 box?

Hey guys, I'm in the process of sending a PS1000 back, but wanted to know if anyone ever had this issue before. Car has been running great for about 5 weeks. The only issue was a hesitation with about 1-2% throttle. Transient maps/timing/regular map changes made no difference. Other then that issue,...

Re: Air density compensation

This is exactly what I was thinking. It makes sense when in VE mode, but regular injection time is raw which led me to think you'd have to program that separately. Thanks again for your insight Matt!

AVI inputs

Hello everyone, Is there anyway to use AVI inputs with a ground signal? Just wondering because the PS1000 only has one DSI. I already have that configured for an "A/C request". I wanted to use more switched inputs to perform certain functions (launch control, ect). Whenever I select an AVI...

Air density compensation

I just had a question regarding air density. I know that MAP based setups rely on the MAP+IAT sensors to determine air density. Does this calculation happen automatically, or do you have to tune something separately. I'm wondering because some Haltech tuned cars I've setup in the past run a bit lean...

Re: inj duty cycle

Awesome reply, thank you! That should clear it up for everyone (it certainly did for me). :D

My only question is the 20ms window for injection. Is that an arbitrary number? I'm assuming there is variation between engines of all different sizes.

Re: inj duty cycle

The way I see how this works, is that the latency is too low. When that happens, the ECU think's it has to keep an injector open longer to offset the latency (even though it's opening just fine). That's how the ECU sees over 100% duty cycle. Like I said, I was tuning a Volvo once and it showed over ...

Re: poor crank timing

Please check the Throttle pump settings Accel Ignition adjust Accel Itnition Decay rate To amke sure the throttle pump ignition adjust is not effecting your ignition timing, Accel Ignition adjust? I'm just randomly looking through my PS1000, and don't see that option anywhere. Is that an R33 box sp...

Re: Idle Stepper Motor Settings

Are you in a really cold climate? I've found the best results just ditching all the idle air components together, and just setting the idle by other means (throttle body stop). If the immediate cells around idle and the cells that it will fall into on decel (back towards idle) are set correctly, it ...
