I have searched but maybe my problem is too basic?
I'm using a 165 ECU, Tunerpro, TunerCat, Datamaster and have burned a few proms starting with a stock $32b and now using the 6E. I 'm a bit confused over the MAF table tuning as related to the two masks, $32b and 6E. The Datamaster Histogram provides the BLM info referenced to cells, rpm, maf. I can see how this may be applied to the $32b mask using the BPW fuel vs Load table, however with 6E mask I'm getting lost? Form search indicates changing maf tables and or the Lv8 AE rate vs temp (funstick AE tuning). My 305TPI is runing rich (12 mpg) and this is confirmed by the BLM and histogram data. I have removed the maf screens and use the K&N filters.
Question, using the 6E bin/mask what table should be used (Tunercat or Tunerpro) to correct the BLM's...I really need a push in the right direction to avoid a headace.

 

You need to rework the MAF tables. The fueling in $6E is entirely based on the airflow as reported by the MAF.

Thanks RBob, will proceed with care.

I also noticed that despite my previous assumptions my 88 IROCZ still had the cold start valve fitted and using the 6E bin may have caused some richness??...I was not looking in the right places.

I was luck to find a 1988 Camaro GM service manual from a web book shop (USD 65.00) this has proven very helpful and has very good info on the ECM. Anyone interested see www.books4cars.com.
