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.

Motor: BMW M20 B25 módosított furattal ( 81 mm ) kovácsolt dugattyúkkal, betûzkarikázott hengerfejjel. Turbo: schwitzer S2B, injectorok 650 ccm, külsõ vastegate ( 35mm ) Gyári IX hajtáslánc, végáttétel 3.91, kerékátmérõ 650 mm. A turbo méretébõl adódó késõi felpörgést szeretném áthidalni ezzel a megoldással. Válaszokat elõre is köszönöm.
