Start this thread with a preamble:
Previous long thread: viewtopic.php?t=5544
The following has been done:
Fuel system upgrade - not working as well as I would like so it is an ongoing investigation.
New coil driver - Bosch 211 - 4 channel
COP units installed
Engine operating with sequential fuel and ignition
Baro sensor ready for install as an add-on
Hall effect sensors for crank and cam shaft sensors - replaces the OEM VR sensors
Operated engine on 36-1 crank trigger wheel with OEM VR sensor. Removed cam shaft VR sensor (sync issue)
Reverted back to OEM 8 tooth crank trigger wheel (no missing teeth) and cam sensor when Hall effect sensors installed
Using Dual Wheel decoder system
OEM flywheel timing marks are a PITA to use. Installed a timing mark system in the timing belt area that is easier to use.
The timing light to be used should be for a wasted spark system, or if an older model with a timing advance dial, keep the timing advance dial on the "0" mark when timing engine.
Timing engine with locked timing. Generally set to "0" degrees, but also make sure that the cranking advance is the same as the locked timing, if not the timing will be an aggregate of the locked timing value and the cranking advance. For example, if the locked timing is "0" degrees and the cranking timing advance is "15" degrees, engine timing will be "15" degrees. This affects the spark table.
Fuel and spark, the basis for going forward. Mentioned the fuel system is being a challenge. Does not maintain system pressure. Investigating but not letting this stop going forward.
Good trial yesterday, working well. Read a few posts on Priming Pulsewidth. This is where the Speeduino fires all injectors ONCE at the start when the key is turned to the ON position. The time for the injector firing is based on the value(s) in the Priming Pulsewidth table. I have been cycling the fuel system and did not realize that this was happening with each cycling. I noticed yesterday that the engine started quite well after the third cycling. The Priming Pulsewidth values are: Believe these need to be adjusted upwards, and once the fuel system is corrected, will replace, or assist in a better engine start maybe in conjunction with the cycling of the fuel pump. Will go through the forum posts to get a sense of what values I should look at.
