Re: Double gap error

Did you sort this out ok?
v twins can be weird, what is the crank trigger as in how many teeth and gaps?
I just had a Suzuki V twin apart and the cylinders may be 75 deg apart but the rods don't share the same pin so it doesnt fire 75 deg apart

Re: Shift Cut ignition retard

Yes 40 or 45 deg would be a good start. I had to use pot to start and stop cut, this is the only option when you are using the S100 as a sequential gearbox controller, it works fine. However there needs to be some rotation of the selector drum for the ecu to detect you are requesting an up shift, no...

Re: Shift Cut ignition retard

Ignition Retard is kinder on the engine, use retard as a preference.
You might want to try pot to start and stop the cut dependant on how much slop there is in the selector barrel.
Sorry not sure about the load cell.
How and what operates the micro switch?

Re: S40 connection to computer issues

Can you use the laptop to confirm what com port it thinks it has, somewhere in device manager or such like this will be found. Then set the DTA software to use that port and then try to connect, this can be found at File/Options

Re: Lotus Twincam

If you intend to test sensor position on the starter motor, you will need to set 'firing tooth on start up' to '0' this should be close to TDC, its harder to explain than do! This is because the ignition table proper is not used until the engine is considered to be running. Your crank trace looks fi...

Re: Lotus Twincam

Yes that's it, once running use a timing light to verify position. I get confused easy when using a wasted spark and timing light (I assume you are not using a distributer for sparks, and are using a wasted spark setup) so I enter 0's into the ignition table and look for the alignment of the sparks ...

Re: Riddle me this? Timing will not change

Or somehow on map 2, not the one you think you are on, I've been caught by this before

Reading some of your older posts I note that this engine is a 6 cylinder twin plug with coil on plug's with built in ignitors. How have you wired this to the ECU?

Re: Riddle me this? Timing will not change

Could you still be on the cranking phase of running, i.e. fixed tooth before TDC
Transition from cranking set too high?

Re: RPM calculated gear to XDASH

I think you need to tick 'use left driven wheel speed' and copy the physical undriven input to pin 31 or I think thats how I made it work

Re: DTA S40 CAN turbo duty

David that is exactly what I was suggesting, just not describing it very well :)
