GTRNUR Posted November 21, 2014 Author Share Posted November 21, 2014 (edited) May take you up on that Mitch. Base on the youtube vids I've seen and the documentation it looks pretty straight forward. I'm just making up the external map and wideband interface looms now. I can't imagine Haltech would have left any surprises for me. Out of the box it should control the fuel pump speed and send the correct TPS signals to the Attessa right? Ive seen lots of other people have issues with these two simple things... Edit: Other ecu's of course... Wolf/vipec etc...

Mitchee Posted November 21, 2014 Share Posted November 21, 2014 High/low fuel pump control is hard set at 5% throttle opening (from memory). The TPS follower for the ATTESA 100% works as per factory, as does the injection duty signal to the MFD. The pre-loaded base map should be enough for you to get started with. Just make sure you load the calibration for your MAP sensor, set your TPS limits, enter your injector characteristics and deadtimes and away you go. Set base timing (i like to lock the CAS all the way clockwise) by enabling the ignition lock and adjusting the trigger angle. Dont forget to set the engine capacity, and if you're running an ethanol blend of fuel without a flex sensor, deduct ~33% from your injection flow rate to allow for the fuel density difference.

XKLABA Posted November 21, 2014 Share Posted November 21, 2014 Sorry for the off topic question but what exactly is the signal that is needed for the injector duty for the MFD ?

GTRNUR Posted November 21, 2014 Author Share Posted November 21, 2014 I believe its just the switch output from injector 1. From this the MFD can calculate rpm and duty. 1 Link to comment https://www.sau.com.au/forums/topic/434511-rb34-24u-rb26-800cc-project-rb-high-deck-engine-and-related-builds/page/7/#findComment-7430037 Share on other sites More sharing options...
XKLABA Posted November 21, 2014 Share Posted November 21, 2014 I have a few spare injector outs can I just connect to one of them Link to comment https://www.sau.com.au/forums/topic/434511-rb34-24u-rb26-800cc-project-rb-high-deck-engine-and-related-builds/page/7/#findComment-7430039 Share on other sites More sharing options...
GTRNUR Posted November 21, 2014 Author Share Posted November 21, 2014 Not necessary, it just connects to Inj1. The MFD does the rest. If you were able to program up an 7th injector channel, it would need to be configured to have the same output pulse width as all the other injectors. Also, you would need to put a load on the output, or a pull up resistor to +12v so the MFD would be able to read the variable PWM square wave.

XKLABA Posted November 21, 2014 Share Posted November 21, 2014 Oh ok, so just splice into Inj 1 yeah I can configure a 7th Inj easy enough but bugger doing the rest of that lol Cheers Link to comment https://www.sau.com.au/forums/topic/434511-rb34-24u-rb26-800cc-project-rb-high-deck-engine-and-related-builds/page/7/#findComment-7430098 Share on other sites More sharing options...
NYTSKY Posted November 22, 2014 Share Posted November 22, 2014 Sounds tough If you need a hand with the Haltech set up/install, don't hesitate to give the support line a call Dirty talk?

GTRNUR Posted November 24, 2014 Author Share Posted November 24, 2014 Sorry no dyno time yet. The Haltech is in now. It idles and revs. Didn't get a chance to drive it anywhere though, nor do anything but do the basic setup on the weekend. With any luck I can take a day or two off later this week and spend some time on the phone with Mitch. AI tell me my surge tank is still 2+ weeks away as well.

GTRNUR Posted February 5, 2015 Author Share Posted February 5, 2015 More changes are still in the works. I've replaced the entire fuel system again after being talked into going down the E85 flex fuel path. So bigger injectors, more pumps, bigger fuel lines, external surge tank and bags of fittings... It takes for ever to get parts up here too. Pay for overnight and it arrives 3+ days later. I've yet to source and wire in a flex fuel sensor, and I've got locate a fuel cooler to mount behind the diff too. The interesting news is that I hope to be getting Mercury Motorsports to come to Cairns to do the final tune and setup of the car. If anyone can get it to produce a good final result, I think they are certainly capable of it.
