Guys, I have a 2002 LS with a BEGi Shanghai kit with the following:
- RX8 EV14 Injectors
- BEGi ECU Reflash
- AEM UEGO
- Ebay Recirculating BOV
- GM IAT on IC Cold-side endtank
- Ebay Catback
- Stock Catalytic Converter
- EGR connected
The car holds 17mm/hg vacuum and boosts fine with the BEGi ECU reflash (using stock AIT).
I switched the ECU to my Rev-built MS2E, calibrated my TPS, connected the yellow wire for my wideband, changed the wiring for the GM AIT sensor, used the basemap timing and found that it doesn't build any boost at all (maybe 0.5 psi).
AFR is good from the base VE table, actually a little bit on the rich side.
I understand that it is the base map, base ignition table and VE table and all and that VVT is gone.
It starts fine, idles fine (12.5 AFR). I can't do VEAL at the moment because all it would do is the area below 100kpa (non-boost area).
Can timing totally eliminate boost?
The car accelerates like a normally-aspirated car and the boost gauge simply refuses to move past 0 psi.
I tried it with EGR deactivated and activated in project properties, but no dice.
Again, if I simply swap back to the reflashed OEM ecu (I kept the MAF on), I experience the awesome boostlies that these cars should have came with from the factory.
Attached are the msq and short data log file from last night.
Thanks for looking.
