HFS-6 on a RX 7 FD3S (rotary)

[Richard L]

Sorry for the delayed reply.

1. Your total fuel capacity is 2800cc/min. Check the cc against the chart on page 8
- 100% water ......... 10-15%
- M50:W50 ......... 15-20%
- 100% methanol ........ 20-25%

Use a bigger jet because the HFS-6 can trim it down electronically.

2. I would put the flow FCM in a dry and cool engine bay area, away from a water spray (car wash) and rain.

3. The tank should be at least 4 litres.

4. I believe I have alredu set the 550/850 on the summer. Please check it just ot make sure.

5. As close to the exit of the intercooler the better.
