Yes that one looks much better.

I've only had a quick look through the code, but can see a couple of generic Bosch functions I recognise.
To skip the checksum on reset, set 3CD8h bit 4.
I've added the checksum calculation and bypass flag to the XDF in my earlier post.

Looks like a good start there :thumbup: You said you used Tuner Pro to download the bin - did the ECU report its hardware and software ID correctly? Are you able to try downloading the bin again, but this time in the Plug-in settings in Tuner Pro, uncheck the 'Read/write data only' option? Otherwise...

What model Saab used a Motronic M2.10.3? Was it the the 9000 built on the Tipo 4 platform? Post up your bin and XDF if you can, I'd be interested in taking a look at it. If the base code is similar to one of the Alfa bins of the same ECU series, I might be able to work out most of your missing ram l...

Yes, they work well with a T56/VN speedo combination.

For a 4cyl you'll need a D1927A module, not D1998A.
They take the same coils as the 3.8 commodores, so no need to buy those from the states too.

And make big changes to the tune because it will be running super lean because of the lower voltage going back to the ECU. I don't know if the resolution is a big problem because of interpolating between the cells. Voltage may be different, but setting the flags for a 3 bar will sort all that out. ...

yes, as long as you changed the MAP flags in the bin to match the new sensor.
The downside is that you lose a lot of resolution.

I was thinking vacuum leak half way through your first sentence
The MAP voltage code is quite likely because of the vacuum leak. Check the MAP reading with the engine off, if it looks normal (~100 kPa), your MAP sensor is probably fine.

An LM1815 and a couple of passives is all it takes to convert a VR signal to 0-5v, so no big hurdle.

Every time our landline rings my daughters race to answer it, hoping it will be a scammer. Their favourite victims are the computer virus calls but they tend to be over-dramatic in their responses so usually get hung up on pretty quickly. My wife was tormenting one of the scammers one day, and inste...
