Will this work

[Civic Dave]

Hello all,

Bit of history, i have a ED honda civic which originally came with dual carbs. i have since done a full engine swap (with all the trims) running off a pair of 45DCOE Webers and a MSD programable Digital 6al2 (for ignition). and have been running it successfully as a daily/auto-x car for about 12 months. and i am in the process of turbocharging it (shooting for 300ish whp) and want to convert to efi. Yes i know i can turbo the Webers but for a daily its not really good (i have done it before).

i basically can pick up a efi intake manifold with throttle body, TPS and MAP sensors all together really cheap. basically what i want to do is use MS for controlling my fuel (will not be using it to run timing, thats all good) with the TPS, MAP and a wideband. how hard will it be to do/ tune.

i know its a bit of a basic question but i need the car done ASAP and cant afford to hit any bumps ATM. just checking as i dont want to interfere with any of the other systems on the car.

Cheers, Dave

Fuel only installs are quite straightforward. In your case, you'd feed the MegaSquirt a signal off the MSD tach output so it can see RPM.

im thinking that it would almost be easier to get rid of the MSD and just replace the whole fuel/ignition setup off the MS. what sensors are necessary?

also im thinking to go with the MS2 for the data logging. any thoughts?

as i said i know these are pretty simple questions but i know nothing about efi (im a carb guy) and need to bounce some ideas off people with experience (most of the people i know are carby guys too) because as i said i cant afford to be held up at the moment as i have a kid on the way

and is it possible to run my advance/retard curve from a magnetic pickup like i do with the MSD. that would make things much easier and allow me to get rid of the MSD without having to change anything

[Matt Cramer]

Yes, see these links for using a magnetic pickup and direct coil control.

MS2 data logging works through a laptop and can record all the MS2's inputs and outputs, as well as some of the calculation variables.

I used megasquirt 2 version 3 on my civic using the stock sensors and distributor. I have a zc dohc with 13 psi megasquirt is perfect for this application

nice.

which sensors did you use, and are you using it to run both fuel and timing?

I used all the stock civic sensors and the map thats in the megasquirt 2 v3. I run fuel and timing and have turboed the engine
