Bots ate up all of the bandwidth setting this month.

It is likely relayed to the automated spammers.

The PORT values are all listed in the manual.

They change colour when the voltage at the processor inside the ECU changes from 0V to 5V.

James

In your Project Properties, enable PORT_STATUS then create a new default dash. It will have indicators for PORTT0 and PORTT2. These show the voltage level at the processor for the crank and cam inputs.

Do not click 'Burn' - this will prevent testmode working.

The relay board is rather an old design to be honest. Using a couple of relay bases and a fuse panel that suits your vehicle is usually easier and eliminates the screw terminals that may be a weak link.

I've seen a few posts recently where existing users have apparently posted some spam.

I presume this is spammers hacking into accounts with weak passwords?

If you have a simple password on MSEXTRA, please improve it!

Looks like you are trying to load a tune from an old custom firmware ?

James

Those old settings are effectively ignored once you enabled "semi" or "full" sequential.

James

I have seen this, but not had time to investigate further.

James

Please record a datalog of shifting through the gears. This should capture the selector input pattern info.

James

Loops need to be used with "bitwise AND" operations and operate independently.

James

I wouldn't expect this to work too well or be difficult to calibrate. The MS3 expects 5V "ratiometric" sensors. (The output they give is a ratio to the applied voltage.) The "5V" on the MS3 isn't precisely 5V but normally that's ok because the sensors follow their supply. Using a...

Which connector pin did you use for your idle valve - is it "FIDLE" or "Idle" ?

The setting needs to match your wiring.

James

Possibly this is a timing light issue. One light I had needed to be set to "two stroke" to work with wasted-spark ignition.

James

I'm sure I posted this already in your other topic a few weeks back?

Configure VVT and enable "Ford Duratec 4cyl" decoder. See if it will work and setup the VVT angle as per the manual.

James

The normal wheel decoders expect a single cam pulse per 720 degrees to indicate phase. As I mentioned in another of your posts, you had a cam wheel that needs a specific decoder. Without that cam decoder working the code will report an error as you have four cam teeth per 720 degrees not the one it ...

Have you tested the ignition using the Spark test mode ?

James

I've seen this with MLV too, it totally filled the hard disk on my laptop while at the track.

James

MS3 is RS232 which expects +/- 7V on the RX wire. (i.e. positive AND negative.)

Some cheapo convertors are 0V/5V and don't do the negative part, that's not real RS232 and likely won't work.

James

Sounds like you have an older version of the firmware installed on your MS3-Pro.

SaveAs your tune and then upgrade to the current firmware version.
