[MS - controlling LPG solenoids]

Interested to see what happens with other builds in this thread, as I'm planning sequential LPG as stage 2 of my build (MS3X). It's a way down the line for me yet though.

Good luck with the builds

[Thor top end on 3.5and MS3x]

The previous owner fitted a walbro uprated fuel pump during the diesel>petrol conversion, so I'll try running with that initially. As long as it has the legs to keep the pressure there at top end

I have ms2 on my p6, ms1 on my 90.

I have to say I prefer ms2 even if it just means I can drive the factory idle stepper, some of the other features are handy too (incorporate afr, the clt/mat correction table etc...).

As Bowie says, support going forward is something that should be considered too. 

If the OP wants to go sequential then they will need ms3. 

I'd suggest having a read of the feature comparison tables here:

http://www.msextra.com/feature-xref.html

And figuring out what is required, what is nice to have, what the budget is and then go from there. 

Have fun! 

 

Definitely planning sequential, and COPs. Never liked the idea of batch fire and wasted spark, it seems so wasteful!

If your buying the top end make sure you get the push fitting that feeds the fuel rail and the rocker covers. The breathers are in different places on the inlet manifold and the oil fill is on the other side and a lot taller

Thanks, good to know!

I suspect I'll be fabricating a lot of pipework anyway

MS3 is massively overkill and complex too.

 

MS1 is all thats needed....

 

Thanks Nige

I'm deliberately going over complex, as I'm intending to go sequential. 

The 3.5 is effectively a testbed to learn the MS, and what I can do with it. A different block will come in the future, once I have got the hang of things.

New to this forum.

We've picked up a 1986 90 that has been converted to V8. Not sure of the history of the engine, but is running terribly on a flapper efi. Compression seems good and even, and once running it's smooth and powerful.

I've found a complete Thor top end, so I'm putting the bits together for a sequential fuel and spark MS3X build. It might be overkill, but I'm planning long term, it won't stay 3,5 forever

What problems am I likely to run into mating the Thor to the 3.5? I'm going to use an electric water pump and controller, to reduce losses (but mostly because I found one cheap!)

I'm new to the RV8 and MS, but I've worked with a lot of jap performance engines and mappable ecus in the past.

Thanks in advance.

I'm planning an ms3x sequential build myself, so will be following this thread with interest
