Subject: 2002 carby to ITB MegaSquirt Injection

This can all be found at: www.designmills.com/wiki/index.php/Electronic_Fuel_Injection. Please feel free to use it or not. Hopefully it will help someone else.



I have decided to go a different route then most and install two indivual throttle bodies (ITBs) instead of a single throttle body and plenum type system. So far everything is working great based on Speed Density (Maifold pressure reading) which many thought would not be possible. I also have a more agressive cam with no overlap which probably makes the situation easier (278 duration, .288" lift). More information to come as I install EDIS spark control. Until then I wont be able to give a full review.

Major parts

2 TWM 2900 DOCE 40mm's (2900 + 2910)
TWM Fuel rail
TWM pressure regulator (2800-6401)
TWM TPS switch and plug
Mangoletsi intake manifold
318 water manifold
Copper pipe bypassing manifold (to heater box)
Electronic under-car fuel pump (40+ PSI. for a Ford F150)
MegaSquirt (MS II v3. keeping distributor for now, future expansion in mind)
O2 sensor (Innovate LC-1)
12' MegaSquirt pre-labeled wiring harness
Mechanical fuel pump blockoff plate
Two Bosch temperature sensors (62110788115)
Painless wiring 7 circuit fuse box (dual relay hot switched relays)
OEM BMW intake manifold gaskets
Injectors (22# Bosch Pink Tops)
Lokar throttle cable 36"
Mangoletsi barb for brake vacuum
Grommets
More band clamps (big ones for fuel pump)
Hose mounting clamps
50mm TWM air horns


Plumbing

EAR-100199ERL - Gauge adapter AN6 male-to-female
230206ERL x 2 - AN6 Fuel filters
AEI-12301 - AN10 10 micron fuel filter
AER-FBM2162 x 2 - AN6 to AN10 reducer male to male
EAR-809106ERL - 90 degree AN6 swivel hose fitting
EAR-310006ERL x 2 - 10ft of AN6 autoflex stainless hose
EAR-800106ERL x 5 - AN6 swivel seal hose fittings
AER-FBM1512 - AN6 to barb
EAR-360165ERL - AN6 to 5/16 hard line
RUS-650340 - Fuel pressure gauge
EAR-985006ERL - AN6 o-ring male straight cut to male AN6


Sensor calibration

The temperature sensors were ordered from my local independent BMW parts dealer. OEM part number 62110788115. They are just the simple one wire-hookup type, the housing is the ground. They were very easy to calibrate actually. A lot easier than I thought. Just get yourself a known working thermometer and freeze and boil some water measuring the Ohm's at 3 three known intervals. Here are my results:

F - Ohms
44 - 1.300
80 - 0.568
185 - 0.73

I then plugged them into my MegaSquirt and they all checked out. That simple.

Z - I just had a look through it, however a lot if it is linked to the video and I kept accidentally clicking it. Any chance everything could not be a link and just have the "See the video" as the only link to th e video and the rest as just plain text?
