hi.
I'm not so good at all the settings yet, in megasquirte.
So I'm hoping there is one here who could help with a complete program from his RV8 preferably 3.9.
As I can adjust redirected from, so it will fit my engine.
This makes it all a little easier for me.
I know no program from any other engine will fit on my engine, but it will give a good start to tune further off.

Bedst regards.

Thing is there are so many variables. So unless you can find one for an identical engine and set-up, it's just as fast to start from first principles.

For example, my 3.5 had originally flapper injection. When fitting my MS2 V3, I dispensed with the injector resistors and the cold start injector, but retained the EAV.

And that's before you even think of B&G or Extra code.

Once you've read through the manual for setting things up from a fresh start, you should have the engine running reasonably well very quickly. Getting it spot on takes rather more time. I'm still hoping to do that one day. :D

Have you got a wideband O2 sensor installed? Things would be very tricky without one.

As Dave says theres a lot of variables to take into account.

I assume its an MS2, if so then load the V2.1.0p code to it or the latest V3.03t to it.
I can supply you with a base map for either of those codes, if you tell me if its fuel only, dizzy spark control or wasted spark and the trigger wheel (36-1 I guess)

thanks
Phil

Hello.
I know I can not get something complete map for my engine that just will work perfectly.
But it will give me a good start to tune further on
Of course, the ignition map and VE map have to be adjusted further
But it's still easier than a blank map for me when I know that it has been running on another RV8 3.5 / 3.9:)

My ignition is wasted spark
trigger wheel 36-1
My injector 200cc/min
Yes I have installed an AEM wideband o2 lambda
It is an MS2 and run with v.2.1.0

Bedst regards.

Phil(extraefi.co.uk) as offered you a starting map above your last post, I would take him up on this kind offer as it will get you up & running, you have a wideband so you can lean off or richen up as necessary to tailor to your engine set-up. :D

It is more than welcome.
I am looking forward to trying it. :D
