The two Hitachi chips look to be variants of the Motorola 68xx series and I have data sheets for them. My first quick glance at the MH614 I thought had fewer pins because all the other ICs were of standard width.

I have some oem tables that are VE. Knowing that the oem are about 8.3msec at 6,000 off the bench testing then if it was a 83%VE then could I just use the rest of the numbers as units of msec., for getting a rough calibration to start tuning with. Or is there once again alot missing. I realise this would be maybe hardly run able, but just looking for a starting place.

Post Script is a graphics programming language which allows scaling of all components - very handy in the days before WinDoze and TrueType Fonts. Today it is used mostly in typesetting applications. A PostScript emulator allows you to read post-script files, and print them on a non post-script printer. ------------------------------ From: Justin Albury Date: Sat, 05 Dec 1998 17:47:13 +1100 Subject: Re: Super chargers + MAP Bruce Plecan wrote: > > If the supercharger is between the throttle body, and engine, wouldn't > a 1 bar MAP work just fine if it picked up the signal at the base of > the throttle body (reguardless of boost?). > Granted a 2-3bar MAP could have better resolution. > Anybody see any downsides to the first sentence > Bruce only one problem.....the computer wont know how much boost is being made. ok if you are adapting a blower to a ecu that normaly wouldnt like boost then probly it would be ok....but seens as though most of us guys on the list play with delco's Id reckon that a 2-3 bar map would be better.......
