Engine Protection feature
Wondering who is using the engine protection feature on the haltech platinum series?
I love the idea, however in my mind it would be nice if haltech had a gauge where we could see what was going on. I would go crazy trying to figure out whats going on, if the engine protection feature kicked in (since I dont carry the laptop with me at all times) while I am on the road.
Anyways, now that the car is back on the road, I am looking into the additional features of the ECU; and would love to hear what you guys are doing/using

It works well but I have run into "phantom" rev limiters because I didn't have it setup properly. One car in particular frustrated me on the dyno for about a half hour. It was my own fault though.
The ECU won't output a signal when the failsafe has been activated, though that's a great idea and should be implemented. You can setup an output for ECU Diagnostic Light though and it will trigger when sensors are outside a programmed range. This only works with temp and pressure sensors though, not AFR.

The system works well hen set up properly TTT set mine up on my fb and when the car was on the dyno it had a massive oil leak and the system kicked in on low oil and he shut it down with no damage to the engine. the coolant temps also have triggered the system and alerted to the problem before it actually overheated. mine is wired to the old overheat exhaust light in the dash which didn't seem to work correctly until the last time the ecu was updated.

The way Haltech has implemented these engine protection parameters is not very good. Oil pressure is not dependent on Manifold Pressure and TPS. It is dependent upon RPM. It is the same thing as the idiot light on your stock car dash, useless. The same thing with fuel pressure. You only have one minimum pressure, On a rising rate regulator you have a varying range of acceptable pressures. The protection doesn't take that into account. If you set the parameter to actually account for an error in fuel pressure or oil pressure the parameter will be going off all the time. I wouldnt be too excited of this feature if I was using haltechs.

Fuel pressure is manifold pressure referenced. The ECU is set with a base pressure and then is told whether the regulator is manifold referenced or not. If it is, it knows what the fuel pressure should be for a given manifold pressure. If it deviates by a programmed amount, you get the fault trip.
I definitely agree there should be an RPM component to the oil pressure trip.

Granted, I dont have the fuel/oil pressure sensor, nor the oil temp sensor.The way Haltech has implemented these engine protection parameters is not very good.

Thats what I figured for water/oil temps. Are you not using the IAT, and AFR fail safe options?
