In many ways the LH 3.1 is a very good thing, in other ways, its a bad thing. On the good side, LH 3.1 systems are typically better MPG wise. Also, the AMMs are $99 or less for brand new Bosch units where a new LH 2.4 AMM will run a couple hundred. On the down side of LH 3.1, the ECUs are very rare, not easy to find and quite expensive when compared to $20 bucks for a used working LH 2.4 ECU. On a side note, the LH 3.1 ECUs are almost bullet proof when compared to pink label LH 2.4 ECUs.

On heater control valves, I pulled out a scamtech style valve in our 92 due to binary operation. I replaced it with a scamtech valve and it worked nice and smooth for a month or so... then it went back into binary mode.

Next up is rancho style valve.
