Almost brand new 305 TPI MAF 700r4 prom which I purchased from a GM dealer a few months ago. AC DELCO part number 01228291

I'm converting to 350 so I won't be needing this anymore. It's only been used a few hours.

$50 plus shipping, paid 90+ from gm dealer a few months ago.







This chip fixes these known problems with the earlier chips.

New service calibrators (Ref: Called Mem-Cal In Shop Manual) have been

1. "Rough Idle" on both hot and cold engine - the idle speed is raised to 650
plus or minus 50 RPM.

2. "Chuggle or Shudder" at low speeds - torque converter clutch (TCC)
engagement speed is raised to 41 MPH.

3. "Hesitation" on light acceleration with a hot engine.

cold driveaway.
