folks are using them on rover v8s, and i know there are a few land rover guys in the UK and south africa whove got them on their rigs.

as mentioned, if you have an obd2 vehicle, its technically illegal. if you just have to pass a sniff test and a visual inspection (pre obd2) then its perfectly legal and can be made to pass emissions just fine.


anyway, not to derail the thread too far

 

Wiring them is not a big deal. Instructions, forum, vendors besides a huge manual. It would be far less work than rewiring an entire home with new 200A main panel. It's all relative. I'm going that route but haven't decided wether MS II or III. The SFI ability is lost once you push the throttle, it then switches to bank firing which is what we have in our OBDII trucks. The fuel savings just on that alone would be minimal unless you sit in rush hour traffic at idle for over an hour a day.

It's illegal on any pollution controlled vehicle period. If you road rally or off road it's not but then you'd have a single use vehicle worth zilch in the dd realm. Now if your state doesn't have inspections who's gonna know so carry on and gain control of an antiquated, low powered, engine management system. Go.

 

go with MS3, there are a lot more features and if youre starting with a new setup you may as well get the latest hardware set.

luckily there are still plenty of opportunities for fuel savings by altering the tune as well... and that you wouldnt rely on sequential injection to provide all of your economy benefits anyway (and i would argue that the benefit of sequential is minimal off idle...)

i guess i should have said if youre pre obd2 you can get it to pass emissions just like anything else... tunes can be made, evap cans can be controlled via MS, etc.
ive built and tuned a handful of cars that have passed emissions in this way. may of which look completely stock under the hood.

 

Eric: Since you deleted your cats, what did you do with 02 sensors and the signal to the ECU?

 

Just reconnected everything as normal. Though I'm considering remove the rear two. No emissions related codes yet.

 

If the front 02 sensors are not in the exhaust stream (are they) what kind of input are they providing to the ECM.

I would think if the 02 sensors do not provide the expected input to ecm, that would be a major problem would it not?

 

Just an update for this thread. Replaced fuel injectors and removed AEL. No change. Codes still present. Maybe it's all in Rovers head...

 

Why don't you stop throwing parts at it and spend some money on a good DVOM and start checking things? Clearly there is something amiss, and only hands on testing will reveal it. Save your money for gas, after you get it fixed.

ihscouts knows his stuff, and he knows who I am. Take the time to find the root cause of the problem. The GEMS system is not all that bad once you understand it.

 

All parts have been educated guesses and part of a rebuild anyways. I took it to a shop with an AutoLogic system and it was not very helpful. I might have to take it back and try again though.

 

Educated guesses? Where was the person who is doing the guessing educated? Did they just start at the cheapest thing and work their way up to the 'spensive stuff?
