ITBs on 4age 16v - suggestions??

[Ian - AE86]

Thanks!!

i have a few other things to check: got some info from another dude on another site so looks like i cud be a busy body!!

"The first step is to get a smooth idle.

you need to get a book and make sure the 20V TPS has the same resistance as the stock TPS if you don't the ECU is not getting the right info

also need to make sure that the TPS is going in the same direction as the stock TPS from high resistance to low resistance or from low resistance to high

the MAP sensor is a Manifold Absolute pressure sensor so you can take from that its hooked to the manifold past the throttle plates.
If all four runners are together that would be best since you would have less pressure fluctuations.

next you want to use the test connector to disable the ECU from changing the timing. just one less thing to worry about at this starting point

so now with the Throttle plates closed you might expect the thing to run rich since no air is being bypassed with an air control valve or Aux air valve

the way to get around that is to have the throttle plates cracked open just a little but don't do the throttle plate thing right away
do the other stuff first and see where your at

you will also need to synch the TB's just like a set of sidedrafts
you would want to set them up to read the highest reading with one of those carb synch tools

I would save the Cam tuning for later (what cams are you using)?

just a few things to start you off

Oh and you would want to lower your fuel pressure you can always raise it back up later.

GREAT!! Time to get cracking with a number of different things!! where to begin since i downloaded teh APEXI SAFC instruction manual and by the looks of the 50 pages u may need a PhD in electronics even to understand the instructions!!!

i luv cars....
