Thanks for the cross reference, I should have though about that
.
Personally I think we should make the whole thing as easy as possible with the least number of components that way more people will want to give it a go and it DIY-EFI will be
the site for yet another aspect of Engine Management.
The more ideas we can get on here with some kind of functional proof behind it would be superb.
now after spending 3 hours outside freezing my nuts off trying to get my engine running on MS2 again to do some knock recording if finally give up because of losing the light and it starting to snow!
I put the OEM ecu back in and start her up to put some charge back in the battery the bloody thing won't idle and I think to myself...Has the idle valve stuck open, have i burnt out a couple of coil packs? no it turns out the pipe that goes from the idle valve to the intake manifold has come off! ahh relief! pop her back on and she works fine.
So i didn't get her running for any longer than a minute and couldn't get the mixture ripe for knock but what i have found is that the line input captures the normal engine noise perfectly. and yes the noise floor moves up considerably when you rev up from idle to 3000Rpm.
the sensors even pick up noisy hydraulic tappits!
so the plan for friday now is to equip a second laptop with the scope software as this tuning laptop of mine P3, 333 with a blistering 192MB ram will have a bit of a time trying to run the scope program and MT at the same time.
I don't suppose there is a way to capture the line in on the sound card in MT as a field for logging with the rest of the data???
