Re: Introduction. 202 red conversion to ITB manifold questi

Interesting couple of days.
Have managed to get the thing running if you could call it that. Had to reposition the TPS so that it was outputting meaningful volts. Now 0.2 volts at 0% throttle and 3.04V at 100% throttle but TP5 still only showing 91.2% when the throttle bodies are to 100%. Still trying to work out how to solve that, I thought there might have been a calibration table somewhere but cannot seem to fine one. It's very rich, especially when the throttle is blipped and the logs show the spark advance looking a bit like a saw tooth. At least it starts and runs but will not idle. I cannot expect too mush at the moment as I don't have MAP or IAC connected. Have ordered a MAP sensor to see what that does even if it is not ideal on ITB's
I would like to run it in Alpha-N but cannot seem to find much information on how to set it up. Is it as simple as hacking the VE 20-100kPa table and making VE a function of TPS (volts or %) and RPM instead of MAP and RPM. If so do I have to do anything to tie the TPS settings into the other tables instead of MAP.
A few problems.
Being able to start it and run it is very unreliable. Sometimes it starts up no problems and other times just won't start at all. When it will not start there is heaps of spark but the injectors aren't firing at all so no fuel which is also obvious by looking straight down the throttle bodies. Then later, without changing anything, it just fires up. Got me stumped.
I've also had a lot of trouble connection to TP5. Most times I get the pop up box with the 8 or so reasons why it hasn't connected. The Flashtool also has some problems but is more reliable that TP5. I suspect my HP laptop and have reloaded the USB drivers but hasn't really improved. I feel there is a conflict in the laptop but haven't found it yet. Also going to have a go on another laptop if I can borrow one.
The ECU seems to be working fine as the pump prime on ignition ON works and the blue led on the NVRam is on and goes off a couple of seconds after ignition OFF. When put into diagnostic mode the check light is flashing as expected.
From what I have read, I gather it should run with the 4 pin connector removed from the BIM146 module. In fact it won't even start, again plenty of spark on crank, (coil HT connected to a plug sitting on the chassis) but again no injector pulsing (led across one of the injectors) Please confirm if it should run with the connector out.
I have the RW link on the NVRam off so it is impossible for me to change the cal by mistake in that state hey ???? Yes or No
All good fun and a great learning curve. I'm thinking it should be good fun when I get the stroker motor rebuilt with the YT Ally head, cam etc and plonk it in the Early.
