When I do the swap, in leu of the EBL flash, would it be best to get the truck up and running with the 7747? I have already upgraded the 7747 (still sitting on the shelf) with a ZIF socket for the SST27SF512 chip, Or just precede with the swap and not look back?
I had the same setup with the ZIF socket in my 7747. Tuned for a while with Dave's help, then went to the EBL and started over. Since the tables are larger, it was easier for me to run the VE Learn on a stock tune that came with the EBL instead of modifying my tune from the 7747. If it were me, I'd jump in and get my feet wet with the 7427. YMMVOriginally Posted by TriumphR3
My setup is similar to yours - Summit Racing 162108 aluminum heads, Lunati bump stick, 1.6 full roller rockers, 46mm TB with an 18LB Spring set at 20 PSI, etc. The 7747 just wasn't fast enough and tables were too small. HTH
Absolutely it helps. Im with ya on the 7427. I can pick one up for roughly $40-$50, And the connectors are reasonable enough at Mouser. Repining, that's the easy part. One question, will i still need the nb02 sensor or will the wb02 (I have the Spark2 and Bosch 4.9 setup) be enough to handle o/c loop modes? Before I punch a hole in my header for the sensor bung. I'm thinking the wb02 is only for data logging and fuel programming on the chip.
FWIU the 7427 only runs INT/BLM on the NBO2 where the EBL can run either. Maybe someone else can jump in and confirm this?
