1994.5 questions

[roddy]

Do 1994.5 -1995 have different CPS sensor than 1995 -2003?
Read somewhere they are different. Current CPS is good just want a spare and which brand / color sensor to get?

My Compressor wheel looks like it suffered from dusting or 338,000 of use.
Which wheel would you recommend for stock setup?

I thought the cps was 94.5-97 but I'm probably wrong. The fellas will chime in and help ya out soon.

94.5-02 cps is the same.

The only issue with changing out the compressor wheel is that the turbo should really be rebalanced so you don't tear up bearings.

x2 ^^ agreed with that statement

There is a different CPS for the Superduty's (99+), but they will interchange.

Only difference between the two is that the OBS one has tin contacts, where the superdutys have gold.

Thanks for the info on the CPS as Ford parts shows 2 part numbers and thanks the turbo info. Read posts on changing compressor wheels... none of them mention balancing.
To re balance the turbo i guess its a bench job may as well let them change the wheel too?
Turbo bearings are tight, no shaft end play or side movement.
Can see where its necessary with turbo at 10,000 - 20,000 rpm

Another question... Have spent a lot of time with AE hooked up & EOT sensor configured to 250F. Noticed that EOT temperature NEVER goes over 150.00F (it does increase slowly as engine warms over 30 minutes or so). Did the test comparing IAT and EOT on cold motor, temperatures are the same. Running working 190F thermostat.
Are EOT's known to go bad?

YES they are if you have Fords software or Snap ons and you try to run a CCT with a bad EOT it won't let you. Bad EOTS cause hard starting and poor fuel econ. your oil temp should be 185-190 Now IAT shouldn't affect EOT.
