Summary of change:
TVR Cerbera fitted with AMG M113.980 v8 engine 5500cc. ECU: VEMS 3.6. Firmware 1.1.96 '''Sensors:''' * MAP: vems internal sensor. * IAT: as sold on vems website. * Coolant: bosch * TPS: nissan * Lambda: 1x bosch wideband * Trigger: Bosch VR part number 0241210171 ** no shield on wire. using original engine loom. ---- '''Sectrig:''' * ECU was configured factory sectrig=VR ** home-conversion to sectrig=HALL was attempted, but '''NOT GOOD YET''' * measured 0.37 volts on EC36/17 HALL input when nothing connected ** that is too low ! Should be 3.7V or higher (min 3.0V, realy !) at EC36/13 (or the CPU side of SJ7) * '''REMOVE THE WIRE EC36/13 to the board''', that goes to the 10k before LM1815/pin3 * see the v3.6 sectrig=HALL on GenBoard/Manual/InputTriggerHardWare (v3.6 == v3.7) Bosch Hall HA-P2 part number 0232103111, no shield on wire. Sectrig working well after following above page. ---- Ignition: -8 x coils direct drive from ECU Bosch twin single fire coil 2x1 part number 0221503035 2k ohm in plug leads. all on seperate channels from ecu Injectors: -8 x Standard Bosch for this engine high impedence 13ohms. all on seperate channels from ecu. Outputs: -Fuel pump relay -cooling fan relay -IAC Bosch double solinoid. running on stepper outputs. Timing: Crank trigger 60-2. Missing tooth at 65 deg btdc. Firing order 1-5-4-2-6-3-7-8 Binary code for knock based on firing order: 10110100 (that is 0xb4 , or decimal: 180 ), but if your ignout array does not start with the ignout for cyl1, that needs to be bitwise rotated before using as knock_chan value. * note: if you publish vemscfg or vemslog, we can help, but even the vemscfg (h[2]=... line) or vemslog is not enough to surely tell that, unless the real cylinder numbering - available in new VT for 1.2.x fw - is filled out properly. Just in case, specify ignout - cyl mapping here: * cyl1 EC36/.. * cyl5 EC36/.. * ...should be on cfg file. **I have now done over 10000km with this cfg on the road! the only things I have noticed is that on average every 1000km it will stumble for a second losing power, similar to plugging in the laptop on the move. not sure why this happens? **overrun fuel cut software can cause odd issues so have disabled. Not to worried about that though. **Cranking seems to take a while before it actually starts. looking at trigger log file (also on the link) you can see both triggers but fuel/ignition takes a while to cut in? https://drive.google.com/folderview?id=0B1bD3kJOFhgZcUJoV3d5bXpETm8&usp=sharing TODO: Knock settings. Runing 2 bosch twin wire sensors. no shield on cable to GND. one wire from each goes to EC18/1 and EC18/2 and both are grounded to EC18/17. is this ok? main problem is software settings, what do i put for (knock chan)? no help menu on vems tune for this. all other input values make sence. many thanks. Contact: chris atbutnossppam kendallengineering.com HELP! 2 injector channels are down. injector on all the time, as soon as you power up ecu. Tested board, both injector transistors go back to the same chip. How can I repair this? thanks.
