I have read about the timing retard and decided to hook up the phone with a bluetooth OBD. Outside ambient in FLorida today was 90F. Cruising steady at 50mph, Intake Air Temperature (IAT) reached 130 F. The timing showed -20 retarded. I was wondering what other people are getting. Speed seem to effect the temps little as it was similar at 65mph. Hard pulls climbed slowly.
I have read other threads and saw that some had good luck with the Johnson CM30 pump to replace the standard Bosch. I dont know if mine has ever been replaced so it could be the old 3 gpm pump in there.
I would like to hear from anyone that has gone down this road ahead of me. This car ( S600 ) has the M275.
I am currently having the same problem. Pulling tons of timing with my renntech tune and need to decide what pump to get. Will the newer 010 Bosch pump be sufficient with the renntech tune, or should one upgrade the pump AND heat exchanger?
I do not know the answer to that. What does Renntech say? I plan to swap my stock cooling pump for a Jonson cm30 as my next step. I dont plan to change out the intercoolers. However, I dont have plans for a HP increase at this point.
