okay fellas ima try to inform yall the best i can...i have an h22a4 engine, but its all took apart...head, camshafts, i/manifold,fuel rail, sensors...

i am missing these following parts

1. EGR valve (the cylinder on the passenger side of the I/M)
2. MAP sensor (right on the top of throttle body)
3. TPS sensor (on the back side of t/b) :issue: i heard this has to be calibrated?? is that true??
4. fuel rail studs (idk why someone wud take em off)
5. iacv (can i bypass this somehow???)
6. main pulley
7. i need to convert an obd2 dizzy into obd1

if its possible??? please explain



i hav heard that there are a couple sensors that i can bypass if anyone knows this method please explain with details...and if you do have to calibrate the tps, how can i do it??...im gonna keep you guys posted with pics and all the goodies,

You can block the EGR valve with a plate. But youll need to use a p28 ECU. P13 will result in a code 12.
Map sensor is required. you can use any OBD1 map sensor. some mount on the firewall with a vac hose attached. Block off the hole on the TB.
TPS sensor can be adjusted. With connector plugged in. Key on engine off, the red wire has to have .4 to .6 volts closed 4.5 to 5 volts WOT.
studs, no brainer. Junk yard or dealer.
IAC, You can block off the IAC, But youll have no idle control. and a check engine light.
Dizzy. To convert, You need to add the blue tach lead to the side of the igniter. also, 12v black/yellow wire. these are on the 2 pin connector on the OBD1 dizzy. GOOD LUCK!

blue tach lead??....do i splice them into the 2 pin wire on the obd2 dizzy???...and wich color goes to what?? thanx for da help civiclude

AccorDitroN

okay chek this out i went and tried wat civiclude said, luckily my old f22 harness has a 2 pin clip for the dizzy and the wires are blue/black and yellow, now my new obd2 h22 dizzy also has a 2 pin clip and same colors...heres a piccc...

okay as you see the two clips go together perfectly so i dont have to splice anything rite?? tell me if im wrong...


also the other dizzy clip on my harness has 7 wires, and the odb2 dizzy clip has 4, how can i splice them together if possible?? or maybe i just eliminate some of the obd1 harness clip???.....heres some pics...

Your better off running an obd1 dizzy, that directly plugs into your existing harness.

The OBDI Dizzy has the coil, CKP sensor, and TDC sensor inside.. the OBDII Dizzy does not.

for an OBDII H22, the TDC/CKP Sensors are located near the oil pump, and the coil is external (mounted on a bracket above the EGR Valve)

However; if you want to go with the OBDII Dizzy, you'll have to do a bit of splicing.. Essentially splice up the matching colored wires; 2 of the remaining wires will go to the sensors, one to the coil.
