Throttle position Voltage output of TPS as a percentage from fully closed to fully open Ignition advance: ignition timing of #1 cylinder Vehicle speed per the vehicle speed sensor
Coolant temp: Value of coolant temp sensor Calc Load: Currrent intake air volume as a poroportion of max intake volume If you have a FSM, you can monitor everything shown on the CARB-mandated SAE controlled DTC chart. **I am not affiliated with PPE in any way, I just wanted the system and negotiated a discount for us all in exchange for posting this here in the forum.** If anyone else buys this and wants my FZJ-80 dashboard, I can email you the file and you can load it up and start with it and modify as you go to suite your needs. Enter LANDCRUISER and when you total your order, the $30 will be removed. When you order and proceed to checkout, it will ask you for a coupon/promotion code. He has agreed to discount the system from $189.95 to $159.95 for Mudders. If you buy it, Palmer will send the interface cable and the licensing to you.
You can download the software and play with it offline for free. It purports to collect the additional manufacturer-specific codes, but from what I can tell on the FJ-80 OBD system, there are only 20 additional codes available and those are basically ON/OFF values that re for the most part, fairly evident anyway (things like AC ON/OFF, PARK/NEUTRAL POSITION, FUEL PUMP SIGNAL). The closest thing I have found to this is the AutoEnginuity system. and build custom dashboards to suite your needs. You can custom build gauge ranges, colors, gauge styles etc.
The system is intuitive and easy to use and allows you to build and manipulate the gauges any way you want. Notice the speedometer and tachometer are identical to the 80 dash. The screenshots below represent my customized gauges I am slowly developing for an FZJ-80.
These 14 fields provide a continuous stream of data which is displayed in a series of “dashboards” which can be shown on-screen either as customized gauges, data logging charts, or cell-based spreadsheets. It also gives engine coolant temperature, ignition spark advance, intake air temp and MAF sensor airflow rate, etc. The 14 fields of available data are shown in the FJ-80 FSM in the EG section (pages EG-222-223 in my 1997 book.) These are the essential fields in diagnosing the majority of emissions-related issues with these trucks, such as O2 sensors. I have negotiated an IH8MUD member discount for anyone interested in purchasing the PCMSCAN OBD-II diagnostic system from Brian Palmer and Palmer Performance Engineering at The system is a PC-based interface to the OBD-II system and allows you to monitor and read the 14 CARB-mandated OBD values in real-time as well as record for frame by frame playback and analysis.
