Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I found a thread about a place in FL that could fix the computer issue of running the stock components if I read it correctly.

No idea if stock DME/EFI could be run on the motor in a bare bones application without resorting to trying to use the 986 gauge cluster and other electronics.

megasquirt should have that ability, otherwise i have heard of folks using window switches to do the same.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Greetings all, Looking at doing a Megasquirt EFI install on a 2.5 I picked to put into a 914 (yes, the motor is super wide and is going to hit the trailing arm mounts so I have to get creative somehow, still thinking and thinking) Why alternate EFI? 1. Motor only came with the sensors mounted in the engine, I have no harness or ECU or intake manifold assembly, going to be costly to gather up all that stuff (MS is paid for, came from another project) 2. No idea if stock DME/EFI could be run on the motor in a bare bones application without resorting to trying to use the 986 gauge cluster and other electronics. If I could just pull the camshaft assemblies out and drill and pin them at an ideal setting that would be simplest solution. Thanks and putting Nomex on!

POST 2Original post

Going that round would significantly limit the power curve on this engine. From the outset, it was designed to have a variable cam profile, so killing that is going to have consequences. Why not find a correct DME, harness, and an intake system from "itsnotanova" who runs a breakers yard for old Boxsters?

I'll reach out to him, thanks. I found a thread about a place in FL that could fix the computer issue of running the stock components if I read it correctly.

POST 4Original post

if i recall, it is just on on/off signal that fires at a certain rpm. megasquirt should have that ability, otherwise i have heard of folks using window switches to do the same. i've also read of track cars that have the cams pinned to the high rpm position - might be a bit gutless on the street however.

It would also be hard starting with the cams advanced.
