3 Bar MAPS
Hi to all! Sorry to reply to an old thread, But felt compelled to answer the Question: Remap Ecu for 3bar map on ALH's (Feb.98 build)?
Answer: NO,
I've been having problems w/1550 code. Had factory Map (20yrs old) kept on "pooping out" (went limp)at 52mph in 3rd, 64 in 4th, 69 in 5th (@ WOT)
Installed NEW 2.5bar map,--little improvement!.......Dropped in a 3bar Map.....
no more "1550"! YEAH! I did NOT do anything but clear the codes!!!!!!
Still did not have the "mid-range power", though......that turned out to be a BAD MAF that was NOT throwing codes (figured that out by reading Forums), replaced it and WOW! And no more 1550!
I noticed a difference in the map readings (b4 starting) btwn the Map's as well as the MAX boost readings, here they are: (all tested@ same time)
INIT Boost MAX (PER OBDII)
2.5 bar (old)- 28.4" Hg ~70.0" Hg (sets 1550) (@ WOT)
2.5 bar (new)- 29.2" Hg ~70.0" Hg (sets 1550) (@ WOT)
3.0 bar (new)- 25.4" Hg ~66.0" Hg --NO CODE!! (@ WOT)
Interestingly, after the new MAF was installed, code 1403 (egr low flow) keeps setting, n18 & n75 are new, valves mech work.
I'm waiting on a Vagcom, expecting it this week(just cleared customs).
I'm reluctant to remap the MAF, though. I'm concerned that it will screw up the balance achieved, causing more 1550's.
FYI, maf reading @ idle(@~170f) ~1.75#/s (new sensor)
I'll update after I get the Vagcom.
CHEERS!
