EFI computer to suit 2TGEU?

[Blue '22]

Hi Guys,

Noob question that I couldnt find elsewhere on the forums...

I am having a rebuild done on a 2TGEU (missing fuel injection setup since lord knows when...)

My mechanic has suggested that I consider installing EFI instead of the twin Solex setup that I had originally planned... I can see the wisdom in that - but I sure was looking forward to the sound of those carbies!

I have been able to source an EFI unit locally in serviceable condition, but without a computer...

Does this mean that I now have to source an original 2TGEU computer - or can I substitute a more modern alternative?

Any suggestions???

Definitely fit a new computer. You can set it for a far better tune than the original computer. There are a few good makes of ecu's out there. You need to find one that is good for your price range. Wolf, Haltech, Microtech. EMS, Motec. You will probably need to change your TPS (throttle position sensor) they don't seem work on new computers think there analog.

If you want to keep the noise of carbies quad throttle bodies is always an option

Cheers

Wish I could afford Quad throttle bodies... might be on the cards for later though! :-D

What would I reasonably expect to pay for a modern ECU? *ballpark*

If you want to go all out you could get a computer to run the ignition and the fuel, to do this you will need to do some fabricating to get a crank/cam angle sensor of some sort. To run the EFI (even with the original computer) you will need to generating some sort of trigger signal to tell the compurter to fire the injectors. The factory EFI set up comes with a reluctor sensor in the dizzy to do this. Unless you source one you will need to create a crank angle sensor anyway and you might as well get the computer to control ignition and get better performance. I'm about 99% finished installing a Haltech E8 onto a 2TGEU so if you decide to go down this way feel free to PM me any questions or if you would like any photos of the set up I'm running.

^^ only if your going to run sequential injection you need a cam sensor or crank angle sensor. The dizzy with electronic ignition will be fine to fire spark and fuel.

I completely agree, but with original factory electronic dizzy in rare supply you can do a conversion to your dizzy or bite the bullet and go sequential. Do a search on the forums as there is a thread that shows you how to convert your dizzy.

Awesome :-) Thanks for the advice guys, that's definitely some food for thought...

I hope I'm not biting off more than I can chew though!

Can anyone recommend a good mechanic/shop in Brisbane (preferably South Side - I live about 1 km away from Slacks Creek) that might be able to take care of the fit for me? I really want to get this project taken care of quick smart.

Cheers!

P.S. I've already had a full rebuild/balance/port done on the 2TG...

Since you already have a sidedraft manifold why not just go with a set of 20V quads, will take a little modding to fit but if you are going aftermarket computer it should have no problem running them. Don't know what your prices are like there but quads pop up here for $100 to $150NZ pretty regularly.

You could try talking to APC (advanced performance center) in Underwood I've heard good reports about them. Also The Brock Shop in Underwood or http://www.hipowerracing.com/hpr/ind...tpage&Itemid=1

for bang for buck cant beat the megasquirt but you kinda have to be smarter than your average bear to put the feckers together and tune them. another option is the adaptronic, features of all those computers mentioned above but at a fraction of the price and in most cases more features than you can poke a stick at

but at the end of the day if you have a set of solex carbs rebuilt or otherwise its going to be far cheaper putting them on and with equally as good results as an EFI setup, what you probably havent thought about; EFI pumps, wiring and installation (unless you can do this yourself), tuning, other EFI bits and bobs like fuel lines, filter, injectors, TPS, MAP sensor.

all of that shit up there adds up REALLY quickly, so while an ecu may seem cheap theres a whole swag of shit left to go with that, im not trying to deter you from going EFI just throwing up an informative and otherwise useful post (not very much like me is it?)

Adaptronic is also a VERY cost effective solution.
They are about $900 to buy.

Also - converting the 2TG dissy to electronic is a peace of piss. YOu can swap out the parts from other similar age toyota 4cylinder electronic distributors (22R, 21R, etc) into your 2TG dissy... and BANG - electronic dissy.
Then just get the mechanical advanced welded (locked) so it is a static signal, and then the new programmable ECU will be able to control ignition timing AS WELL as fuel mixture.

Having taken an 18RG from carbies to factory ECU to a full programmable fuel + ignition ECU (megasquirt) I can safety and comfortably say that the full programmable option is BY FAR the absolute best. Driveability is improved in leaps and bounds over the standard ECU and carby setups.
