So from my undersanding MSII should allow you to synchonise the MAP sampling at a particular crank angle
I'm using Tuner Studio and MSII v8.89 and I have EDIS 4 ...

anyone know about SyncroMap?
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

Re: Still having trouble tuning - the never ending battle
I ‘m sorry but I still cant get my head around it.
The Pure AN to Blend & SD thresholds are both based on RPM.
The car idles between 68 and 70 kPa at 750rpm.
If I blip the throttle at idle the map will immediately shoot up to 100Kpa while the RPM bearly moves past 700 to 800 rpm for a ...

Still having trouble tuning - the never ending battle
I hope someone can help with this and I apologise in advance if my questions are a little lame.
I’m still having problems with tuning.
I’m going to try Alpha-n only to see if that helps but in the meanwhile, I’d like to exhaust all avenues with Speed Density and Blended Alpha-N – which ...

Re: poor idle and high revs
seem to have resolved the last problem i was having,
As I mentioned earlier, I’m using Suzuki ITB and I read somewhere to use the Suzuki Vacuum damper that comes with the TBs – to smooth out the signal.
I don’t know what is in this little device, but it somehow caused the map ...

Re: poor idle and high revs
thanks for your help
I uploaded the MSQ file.
When I enter all the relevant parameter and generate the VE table the bins are way too high at idle (~30) so I found by dropping them to around ~20 the car will idle ok.
I set the Acceleration Enrichment off by setting the upper and lower RPM ...

Lean condition when bliping the Throttle
I'm running 4 Independant Throttle bodies, MSII and 2.86 of the code.
I have 3 questions I'm hoping someone can help me with.
1) with Acc Enrichment : the Tuning Manaul suggests starting the TPSdot threshold at 1.0 and to try to keep it below 2.0, while the tunerstudio mentions the ...

Re: How much should AFR fluctuate at idle?
mine does too, jumps anywhere between 13.5 and 14.3
I'll be interested in hearing if you find a soliution for it

Btw, i'm also thinking of Blended Alpha-n. I have MSII 2,8 and I've heard its much simpler with MS3.
I've read a bit about MSII and blending but i must be dumb cause ...

Re: poor idle and high revs
As far as it running better with lower VE values – I think I was just kidding myself … Yes its better, but still worse than what I had with the carbies.
I may not be describing the problem properly ...

Re: poor idle and high revs
Everywhere I look I see warnings and disclaimers about running lean and melting pistons,
so I’m a little nervous about it.
Also the WB was installed in the car for almost a year while It still ran on Carburettors and it seemed to be working ok Up to a week ...

Re: poor idle and high revs
I still haven’t ruled out a leaky manifold gasket causing a rough idle. I’m getting a new one and I’ll try it this coming weekend.
Meanwhile I took some of Bluehazes’ suggestions and did notice an improvement - but not a total fix .

Vacuum Leak
The though did cross my mind, I checked all the vacuum yesterday hoses but I can’t really see an issue.
I built a vacuum plenum with all the throttle bodies plumbed up into it and the MAP sensor hose comes off it and goes to ...
