Happy new year!

I am planning to switch over the rally beast to EFI, so i would like to see if anyone has feedback on how best to do this. The brickboard is all over the place on this. I have the intake and fuel rail from a 740 turbo in great shape, and Regal Tuning can port and polish it for me, but is there anything else I need besides a cone air intake and a standalone fuel management system? Which Standalone do you guys suggest?

Thanx:

I am also ordering a:

Houston... you have to pay attention around here, we just had a huge group buy of clutches...

To convert to EFI from K-jet, you'll need more than just what you've listed...

Intake manifold, throttle body, fuel rail, injectors, fuel pressure regulator, and fuel lines to get from the K-jet fuel filter to the rail, and back to the return line. Obviously you'll need intercooler piping and a throttle cable to match the manifold.

You'll also need coolant and air temp sensors for whatever standalone you want to use. Also a throttle position sensor, and unless you're running Megasquirt you'll probably need a MAP sensor as well. You'll want an LH distributor, or if you're running Megasquirt you can use EDIS for distributor-less ignition, which would require one of Dale's adapters, an EDIS trigger wheel/sensor/module/coil pack/plug wires from a '90-92 Ford Escort.

If you're running a standalone, you'll want a laptop and a bit of dyno time to properly set it up so you can beat on it without worry - if you're setting it up yourself you'll need a few weeks of daily driving to get everything right.

If you're going to do LH2.2 (which isn't a bad idea if you're making less than 300 hp) you'll want the AMM, knock sensor, temp sensor, throttle switch, proper LH distributor, EZK (ignition) and LH box, plus preferrably the wiring harness from a late '88 to late '89 car.

I've run the Megasquirt myself and so has Dale. I've used it on a couple of naturally aspirated engines and a couple of turbo engines, and Dale's used it on one of each (though I've set them both up for him). Athal and Geoff have both done the LH2.2 swap into early 240s, and Brad has swapped over all the Turbo stuff into his later 240, and has plenty of experience with the LH.

LH offers the factory tune in a bulletproof package, and chips are available. It's got limits to what can be easily done (200 hp wheel, or so, safely, 220 hp ragged edge) and if you want more you can hack into the AMM signal and install slightly larger injectors for up to about 300 hp (not sure about safety, though - that's pretty ragged edge there.)

Megasquirt offers no limits, but each modification you do requires manual tuning changes, and it doesn't have the stability or reliability of the factory system, so the car WILL run differently at different temperatures and altitudes. Not that the car will not run, but if you're really picky about things you'll notice slight differences. Similar to what the factory must do when tuning their own cars, you should set Megasquirt up to be slightly conservative so that you can safely beat on it under any condition, and sacrifice 2-5% of the power/economy in doing so.

IMO if you are to go to efi, something like megasquirt would be the easiest most cost effective route. I was looking into swapping an lh system into my car but after taking a look at all the wiring involved i decided it wasnt worth it.


But as matt mentioned tuning is quite the task, im on to my 26th variation of my setup. but if you can score some dyno time you'd be set.

On a side note i just recently went to a palm set up for tuning so i no longer have to lug around a laptop when doing minor tuning!

You didn't have to do any wiring when installing your megasquirt, John? Sweet, you've gotta show me how you did that!

thus the 26th variation...i think he add's one wire at a time

ciao

Thanx for all the info....it really helps when you are trying to do modifications with little knowledge about cars!!

LOL well with all the pretty color coded diagrams i found it pretty straight forward, i wouldnt even know where to begin when swapping an lh comp in.

the palm idea is pretty cool, although it is lacking in some areas, thus far only older palms (ie Palm vx, iii,iiix, 500,505, etc) with serial cradles can be used to communicate with the MS, all you have to do is update the Operating system to 3.5 or higher download palm tune and either buy or make a db9 null modem adaptor. I havent really had time to tune with it yet but the step up it pretty straight forward and cheap- earlier palms cost about $30 at a pawn shop.

(ps sorry for the thread jack)

Where does the palm tune lack? I could go this route easily with myself. I can guess it wont be good for the preliminary tunes but quick tweaks later on it would be good

well i think it has more to do with the actual palm, ive just looked around in the palm tune a bit without connecting to the ms and im having trouble getting used to working with the yellowy/black displays of the old palm, some of the readouts are hard to read. and it doesnt have much room for displaying data on the screen but i might be able to improve this as i was reading there is a hack so that you can have the palm in landscape mode. Ill do some tuning on it in the next few days and report back on how the actual tuning feels.

but i think its a great cost effective way to always be able to tweak your MS without having a big and sometimes expensive laptop sitting in there



oh yea and i almost forgot a great feature that has been designed for it, is logging. the palm stores the data and then you hook it up to your pc and it kinda acts as a super fast ms ecu and runs the log throug so you can upload it to mstweak etc.

very cool, good thing i have a palm 3c lying around

LOL, it is cool and I also have a 3C sitting in a drawer, laughing because the 3C is almost the size of a laptop

awesome, the 3c is compatible with palmtune. Im going to post a step by step DIY guide soon, based on info ive collected from msefi.com
