I've stubled on this site =_ http://www.synchromap.com/ .
It talks about Bruce's SyncroMap, does anyone know about it?
is it available?
it could be a good alternative to Alpha-N for those of us struggling with SD on ITB
anyone know about SyncroMap?

Re: anyone know about SyncroMap?
Like you, I am also interested in Synchromap as I have a set up with long duration caams and ITBs.
I have spoken with DIYAutoTune and they advise that Synchromap has not been commercialised. Hence there is no kit or printed circuit board available from them.
Under the subject of "Map Mixer", DonTZ125 has posted a schematic drawing of the circuit in a .jpg file. With a little bit of work you can also determine the component part numbers. The schematic appears to have fewer chips than as shown on the photo in www.synchromap.com. So maybe there are some variations on the wiring. The photo also shows that Bruce Bowling and Al Grippo have had a circuit board made for Synchromap. I am not sure if it is available from them. Alternatively, you could use a universal circuit board or have one printed.
I cannot find any detail on where Synchromap connects into MS-II which is the ECU that I have. I can only assume that the output from Synchromap could be wired directly into the MS-II board in place of the original MAP sensor.
The Synchromap website indicates that the code for MS-II has the facility for adjusting the timing at which point the pressure is sensed.
Any further help would be much appreciated.

Re: anyone know about SyncroMap?
Y'know, it's amazing the stuff I have cluttering up my hard drive ... 
And yes, the "Out" pin connects to the 'Pin 1' hole of the on-board MAP sensor. If you want, you could duplicate the MAP filter circuit in the proto area, run the sensor Pin 1 to the filter, and then from the filter to JS4 or JS5 - constant baro. Don't forget to disconnect the vacuum line from the on-board sensor ...

Re: anyone know about SyncroMap?
Thank you for the information and the prompt reply.
As the ECU will be mounted about 1.5 meters from the engine and the MAP sensors will be close to the inlet manifold, I am thinking that it may be best to stay with a standalone unit. It would also be easier with my limited knowledge of the system.

Re: anyone know about SyncroMap?
If by standalone you mean the SyncroMAP circuit in its own box, I completely agree.

Re: anyone know about SyncroMap?
Thanks DonTZ125. Having just realised the difference in the circuit as shown in your sketch, yes, it is amazing what you have in your hard drive!
The standalone unit that I was referring to is SynchroMAP.
A couple of questions about your circuit. The diode BZX55C12V goes to earth on the bottom leg? Is the power supply for the MAP sensors taken from the Megasquirt supply to the built in sensor or from where the above diode is connected?
Thanks "old guy" for the link to a member with pc boards for sale.

Re: anyone know about SyncroMap?
Not my circuit, just something I found here a few years ago. The 5v for the sensors isn't shown. 4 sensors is a bit much for the Vref supply, so you might consider a separate supply in the SyncroMAP box.
