What do you mean by these? Do you mean you made your own version of the MS main board and the peak&hold board?

No of course
I mean that my MS2 was bought as DIY kit with B&Grippo boards
peakhold driver was built on universal model board

Hi
I have did some mods with MS settings last weekend/ but did not get good results
I started sort out potential faults.
At first
my cam vernier pulleys create a lot of noise sound/ teeth were wornt out because it isnot properly made/ i d changed oem parts/ i used it on stock marks with Schrick 268 deg cams (10.4 mm) not agressive for stock head internals. I tried to install without big overlap, i thought that it may be cause of twitching and drifting RMPs on idle
I changed original double throttle body (oO) to same but with earlier opened small blade for cruising.
After that i get more :oops: problems with idle stabilization. MAP reading became higher 45 Kpa ( 35Kpa before mods). I decided that it is air leak between intake manifold and throtlle body AND/OR air leaks through the gaps between the housing and blades which not properly adjusted. I modded old TB and put with thin layer sealant :oops: No success - I was wrong.
Then i d changed cams adjusting to one teeth of both cams to reduce overlap. it was cause of high MAPs on idle. No TB and air leak detected
I tried to delete vacuum pipe from fuel pressure regulator 3 bar and pressure became 3 bar constant without vacuum regulations. i think it is main cause driftings RPMs on idle/bacause this volvo bosch dual spray injectors was adapted by factory for 3.8 bar/ not for 2.4bar
Pulse width of injectors bacame from ~ 2ms to ~1.6ms on idle. Now i have got smooth idle on AFR ~17 :yeah!: as experimental
VE table cells were tuned for more fuel
