Overview of state of integration between rusEFI and all kinds of ASICs.
## Low side+
2021-02-09 10:40:54 -08:00
2021-02-09 13:50:07 -08:00
### Mostly implemented
2021-02-09 10:40:54 -08:00
2021-02-09 13:49:42 -08:00
| Part | Function | Notes |
|------|----------|--------------|
| TLE8888 | System basis chip | Linear regulator so it gets warm<br/>(with adequate heatsink this is no problem) |
| MC33816/PT2001 | Low impedance (fast) solenoid control: GDI | GDI low priority |
| TLE6240 | 16 channel low side | |
| MC33810 | 4 low + 4 ignition pre-drivers | |

2021-02-09 13:49:42 -08:00
| Part | Function | Known issues |
|------|----------|--------------|
| MAX992x | VR | 85ms threshold timeout means it doesn't work well with low tooth-count wheels (cam, Honda) |
| CJ125 | WBO | Legacy - unobtanium |
| HIP9011 | knock | Not great compared to software implementation |
| MAX31855 | EGT | Not used by anyone |
| [MC33972](https://www.nxp.com/docs/en/data-sheet/MC33972.pdf) | Multiple switch detection interface | EG33 board |
