Visit Preferences to set your user name Summary of change: '''BMW 6cyl firmware upgrade from 1.0.46. to 1.1.18''' note: It might be a good idea to avoid accented characters in page titles * 6 cylinder ** firing sequence, 1,..... * primary trigger: 60-2, VR * secondary trigger: not used * ignition: 3 power-output channels, wasted spark '''Ignition output channels. PLEASE SORT TO FIRING SEQUENCE, and WRITE CYLINDER NUMBER TO EACH!''' * EC36 Pin10 ignch7 * EC36 Pin34 ignch2 * EC36 Pin36 ignch3 Please '''verify that the chosen channels are power-outputs'''. Measure (with ignition ON, but engine NOT running) that voltage between +12V and the ign outputs is 0 (a logiclevel output pulls down to 0V when inactive, so that would measure 12V !) 1.0.46 firmware works great with * ignchmax=02 * h[2]=07 03 02 07 03 02 .. .. 1.1.18 firmware plan: * ignchmax=05 * h[2]=70 30 20 70 30 20 .. .. * h[1]=28 14 00 28 14 00 .. .. ** important: you might need to rotate either h[1] or h[2] to get the spark to the right cylinder(-pair). Document the wiring above (write cylinder-numbers) so we can give better hints Engine does not start, shows wheel-error. '''Trigger hints:''' * normal tooth width: 24 (=0x18, since 6 degrees) * missing tooth width: 72 (=0x48, since 18 degrees) * engine phase when to reset: 160 (reset_engphase_after=A0), though this should not cause no-start ---- '''Analog input''' * MCP3208 '''ch6''' connected to EC18pin .. ** ALS or launch works well with this (if channel 6 is selected) ** TODO: verify that it measures +5V when not pulled down externally ** measures ... V when pulled down externally with 1kOhm (you can use other resistor from 100 Ohm .. 10k, just document) * MCP3208 '''ch7''' connected to EC18pin .. ** TODO: verify that it measures +5V when not pulled down externally ** measures ... V when pulled down externally with 1kOhm (you can use other resistor from 100 Ohm .. 10k, just document) ** neither ALS nor launch works if channel 7 is selected. What can be the problem ? *** maybe input was killed ? The mcp3208 inputs are very sensitive, connecting to +12V or electrostatic discharge can damageit. You can upload the dump and logs via FileArea ---- '''NOS thoughts''' * NOS output control * and RPM and MAP (TPS?) ranges BMW M20 B25 (6cyl, appr 2.5L) modified bore ( 81 mm ) now competing in 200m and 400m dragrace (earlier it was a rally car with restriction before a smaller turbo) * high-grade forged pistons * fire-ring-headgasketseal * injectors 650 ccm * factory IX drivetrain ** final drive 3.91 ** whwel diameter 650 mm * Turbo: schwitzer S2B ** external wastegate ( 35mm ) Would NOS be useful to kick in for a short time after launch ? During launch, engine RPM drops so low that turbo doesn't work well for a short time. When the turbo spools up and boosts, NOS could be switched off. '''Would this be useful ?''' Not sure why he does not use higher launch RPM (maybe he fears the clutch would explode?) ´ Be careful with nitrous oxide if the engine bogs down on launch, even a small nitrous shot will give a very large boost in torque at a low rpm. The cylinder pressures could get very high and detonation can easlily occur. -Jörgen ---- '''Choose output for N2O''' - see GenBoard/Manual/DigitalOut/Table The guy who installed did not document the wiring. We reverse engineer from the mcd/mct dump. This is a 6 cyl engine. The 0F in h[0] looks like it came from a 4 cyl engine. (Roland has a strong 1.8L 4 cyl BMW turbo) h[0]='''0F''' 00 00 00 20 '''80 10''' 00 * injectors A-B-C-D are apparently fired in batch (all 4 at once) ** how are injectors connected ? Why are 4 injoutputs fired at the same time ? Why not 3 or 6 ? * act_rpm_channel=50 mask 0x80 (128) = EC36 pin 17 Inj H * als_tks_channel=60 mask 0x10 (16) = EC36 pin 9 Inj E '''N2O enable''' * mask 0x20 (32) '''EC36 pin 18''' Inj F ** '''choose
