well im getting alot of diff anwsers and well i dont know which is right . Im going to run HO cams on a 2.4l . do i need the cam sensor to run them ? some one told me that to run them just remove the cps code and just tune the ecm ? but ive always heard to install a magnetic pick up on the HO cam and the CPS on the cam tower. with that i dont know were to buy it or how it has to go on there. is there a specific way that it has to be installed ? thanks to anyone that tryes to help me.
you should keep the Cam sensor.
From the looks of it to me, the system is set up to run better with it than without. With= sequential injection, without= batch fire
But what you suggest is entirely possible if you wanted to do so.

Has anyone done the swap ? it seems like if theres no answer out there. has anyone had HO cams running with the CAM positioning sensor ? cmon guys.. thanks

What swap?....... HO Cam?, w/o Cam Sensor?, HP"fixed" for no sensor?
"has anyone had HO cams running with the CAM positioning sensor "
Yes, probably a dozen that I know of.

if i remember right the removing of the code for the cam sensor through the software wont pass some emissions tests correct?
Sven you totally quarterloafed your computer..
yeah i meant to say the HO swap with .410 lift. I dont really care if it passes emitions or not. i just need it to run properly . how is it that the pre 95 dont use this ?
they use batch fire

yep....
do a google search of Sequential Fuel Injection, and Multiport Fuel Injection (I think thats what you call Batch Fire..... ?)
I believe the reason for the SFI is:
- Better gas milage
- Cleaner Running (better emissions)
- More Controled Performance
If I had another car to mess with, I'd give running the HO cams w/o the sensor a shot..... just to see how well it ran. (with the HPT of course)

Is there anyone who can mod/ knows of a shop who can mod the intake cam and tower to run the CPS? I've decided against running without it.
Shoot Zyaaa a message iirc he might know some place.
I can do that.. PM if interested looks like we are not too far apart either...
I have been meaning to disconnect my cam sensor and tune my car without to prove it.
People have done it. One person was having some issues that they thought was because of it, but I think more to the tuning.
FU Tuning
I'm just trying to make tuning less of a headache, by making the process of figuring out fueling a little bit easier on myself since i've decided to give HPT a try and tune my car myself. I feel like it's something anyone who plays with cars should probably know.
dont need the cps pad to tune and have it run fine. 548whp.493wtq here and not a complaint
Yeah. it (the cps) is not used above 1850 RPM (IIRC)
