Thread: Megasquirt computer

you will find it hard to just cut and add....

A mate of mine did a Bosch D-jet conversion to mega squirt and it was alot of work...

Take a look here MegaSquirt® EFI :: Index

It's the future of fuel injection....once people work out how to use it!

I fitted a megasquirt to my 3.5 Rangie.
It was actually quite easy. I had an old ECU from a BMW that had the same plug so I used that, and yes it was just pull out the Lucas and plug in the MS. The software that you get, MegaTune, will basically take the original base map and tune it for you as you drive.

However, I've now got a 3.9 Rangie, dual fuel.
I can't find a plug to wire up to, so I'm wiring it up to the existing harness. I know there are more issues to resolve, ie. the idle control is much more complex on the 3.9.
I haven't done a lot yet as I run on LPG 90% of the time. I've also got to resolve how to wire up with the changeover switch to run petrol/LPG.

Then I can change over to computer control ignition and then have different timings for petrol/LPG.

Still plenty to do, but now I've got a new laptop that doesn't have a serial port so I have to resolve that issue first.

Will report back when fixed, but yes it is worth it.

You buy a USB to serial port adaptor

ytt105 I'd be very interested to hear more when you sort it out

Thanks Streaky. I've had a bit of a read through that today. Will read it in full when I get the time.

I have just finisehed converting my 93 4.6ltr rrc to crank trigger and coil packs. Plan to start tuning it this week. The difference in idling and starting 9both hot and cold) compared to the factory ecu and wolf3d ver3 ecu is night and day. Im using a wolf 3d ver4 ecu to run it. Currently runnig a 4+1 trigger disc and plan to upgrade to 36-1 when i get a bit more freetime. The 36 tooth trigger will allow more precise control of fuel and igntion timing.

With the engine idling in sequcial injection mode the idle is super stable and smooth (it'l happly idle at 500rpm in drive with no idle control applied to it) with the ecu set to bank fire mode (as per the original Lucas ecu) the fuel mixture fluctuate and the idle speed begins to wander.

I can wait to get the car out on the road and test it out
