 Posted: Mon Apr 22, 2019 6:01 am Post subject: Fuel Injection Question |
 |
|
I've currently got a set of Empi 40 IDF Carbs and would be perfectily happy with them but recently i've had the idea of selling them and moving into the 21st century with an aftermarket Fuel Injection setup. I found a company that has been mentioned on this site (on the vanagon side) diyautotune.com and this is what they've given me.
$388.00 MicroSqrt8: Assembled ECU (includes 8 ft / 2.4 m harness & tuning cable)
$67.00 GM3bar-map: MAP sensor
$12.49 GM3bar_piggy: Pigtail connector for MAP sensor
$18.99 CLTIATwPiggy: Coolant / Oil temperature sensor
$22.49 IATwPiggy: Intake Air Temperature Sensor
$9.49 38NPT-Bung_A: Aluminum bung for IAT sensor (Also available in stainless steel)
$22.49 USB-2920: (Only needed if your laptop doesn't have a true DB9 port)
$540.95 Subtotal without wideband or fuel system
For fueling, I'm thinking the 19 lb/hr injectors from a 5.0 Mustang would be fine, along with a Walbro GSL392 fuel pump.
The wideband oxygen sensor system is optional, but a very useful tuning tool. We carry the Innovate line.
Wideband Options:
$189.00 (Special sale price - $166.00) LC-2 without gauge (you can still view real-time AFR and datalog AFR through your laptop)
$219.00 (Special sale price - $198.55) MTX-L Plus digital gauge system
$219.00 (Special sale price - $209.00) LC-2 with DB digital gauge (available in red, green, or blue)
$259.00 (Special sale price - $207.20) MTX-AL analog gauge system
$349.00 (Special sale price - $279.20) LM-2 basic data logger with one sensor
$399.00 (Special sale price - $332.99) DLG-1 dual wideband package with digital gauge
$479.00 (Special sale price - $383.20) LM-2 deluxe kit with one O2 sensor
$669.00 (Special sale price - $535.00) LM-2 deluxe kit with two O2 sensors
now I understand that I would still need injectors and a fuel rail of sorts, but other than that am I missing anything? This is just a thought exercise in cost's so just throw out ideas.

I’m a fan on the Innovate LC-2. Did it on my bus a few years ago, still with stock FI..
My write up,

Defiantly shop around, eBay and Amazon have good prices with the gauge. Also it comes with the o2 bung

Also if you are aircooled you may not get any benefit out of the coolant/oil temp sensor as part of the New FI system. Oil temps are not directly related to head temps or as similar to relationship of coolant in a regular motor.

It's a stock 2.0 type iv, as far as intake manifold/throttle body these are the parts that i'm working on figuring out. I've got an automatic transmission so I don't have the typical throttle cable so i'd have that to work out as well. Also I have none of the original FI parts so i'd have to source all of them (or make one)

He does need something to base the warm-up enrichment off. Something really dynamic like head temp would be ideal but even oil temp would work.
Mario has some nifty stuff for sensing engine temp for the WUE:

If fact, kerian159, that site has a lot of MS-ACVW specific stuff you can drool over.

Well all of this is currently a pipe dream of what I could do if I had the $$ I kinda like the type iv kit since it basically comes with everything i'd need to do it. When I got the bus it had a Weber 32/36 progressive kit on it with the throttle ran to the stub coming off the transmission using safety wire (what i've been using technically with all carb kits i've had on it). So that part is going to have some engineering to make work regardless.
