That's much lower than I expected so just as well I asked. Many thanks Steve

Standard 3.9 serpentine V8. What is the maximum revs I should take it too? I have the option to set a rev limiter but don't know where to set it. Many thanks Steve

I have seen their advert before but on every occasion, as now, they have been 'sold out'. Steve

I was aware that in running MSII I would be in the minority. I suppose the lack of answers to my questions demonstrates the magnitude of my crime. Steve

Would it not be better to know the temp of the oil returning to the 'box? That way you would know that no matter how high the 'box temp was going the cooler was dealing with it. Steve

It could just be a lazy/sticking hydraulic lifter. When the engine is stopped some of the valves will be held open which is applying load to the lifter. While sitting there the oil can bleed out of the lifter. When you come to restart that lifter will have play and rattle until the pressure builds up again in the lifter. That does not however explain why it will start again whilst driving. Steve

My thoughts went towards an exhaust leak at the manifold but you say an oil change cured it for a while so that would rule it out. What oil did you use? For this older engine I would think you need to use 20/50. If it is a tappet type noise then you may be losing a cam lobe which is quite common. The noise is there because the wear is outside of the range the hydraulic tappet can deal with. Steve

To expand on the short and sweet response there from FF the sensor is moulded plastic and completely waterproof. It's connector is also pretty good depending on how well you fit it to your wiring. Steve

Following my logic of how it must work. Pipe connects to the compressor side of a non return valve into the tank. Other end of pipe into switch. I assume when the pump comes on the switch must wait until pressure is detected on the small pipe at which point it closes the pipe so it does not continue to vent pump pressure. So if left open to atmosphere it will just continue waiting and never close off that fitting but the pump will still be running. Does that make sense? Steve

Me again with more questions. Thanks Nige for the .msq. Could not load it as it was MS1 but have opened it in MegaTune on my desktop PC which has allowed me to compare it with my version on the laptop alongside. I do except that there may well be a mismatch and that in itself may be why some of my questions seem a little strange. So to the questions. They may be a little random but they came out of trying to load the different parameters into MSII. 1. What is the max revs a standard 3.9 Serpentine will go too without pushing it too far? 2. The above comes from setting a rev limiter but has the next question of which type, Spark retard or Fuel cut? The msq from Nige has fuel cut but with 6000 and 500 rpm which means it will cut the fuel at 6000rpm but not restore the fuel until the engine gets down to 500rpm which I would expect to cause a stall. 3. Acceleration enrichment. Nige’s msq has this starting at 2500rpm. I would have thought you need this to come in way before that particularly on a manual where you want some grunt from low down. Any thoughts? 4. The msq from Nige has one of the base ignition settings ‘Coil Charge Scheme’ selected as ‘Standard Coil Charge’. I don’t know for sure but thought Nige was running Edis so would have expected Edis to be selected. Any thoughts? 5. The msq from Nige has no battery voltage compensation set in Dwell Settings. Any thoughts? 6. Injection control. Should I use 2 or 4 injections per cycle? The manual advises 2 but has 4? 7. Idle control. I have fitted the Bosch valve and set up the % of air across the temp range in MegaTune. In the msq from Nige the last value is set too 2% which may answer the question….How do I set the normal idle at running temperature? On my 3.5 there was a screw in the throttle body which allowed air bypass for idle control but this is blanked off on the 3.9. The thread may well have been machined before the blank was fitted but I don’t want to dig the blank out and perhaps mess things up on the offchance. The alternatives are to use the PWM idle which would mean the valve is chattering away at all driving conditions or hold the butterfly open with the throttle cable which is not very accurate or repeatable. 8. Last one. The msq from Nige has Hot ASE disabled. Is this to do with the IAT sensor heat soak problem that has been discussed or do we just not need it? I have installed my IAT beside the filter which is under the front wing so away from most of the engine heat. Sorry it’s rather long. Steve

If you don't think the sand will work then fill it with lead. Steve

Learn something every day. Did not know it was to unload the compressor but that small pipe connects to the non return valve which is where the compressor outlet connects into the tank. If you don't have that already then I don't know if the switch will still work without the connection. I suspect it will because in it's correct application there may or may not be pressure on that line but the switch will still work. Steve

The pulley mounted trigger seems to work for a lot of people so why do you think it will be vulnerable? I have just fitted the Ford Transit pressed steel trigger wheel which wraps forward around the pulley. Once fitted you can fill all the gaps with mastic so mud cant build up in it. Steve

The whole ECU could be corroded. Have you had the lid off? Steve

Was actually thinking along the lines of using someone else's finger. Yours will do. Steve

You have not said what year this is. You say you have replaced the relays under the seat but one of them is not a relay it is a diode pack. If that has been replaced with a relay then the system will not work even if that was not the original fault. Was the ECU submerged? Steve

Engine number should be behind the dip stick on the top face of the block. The block may have been machined in which case the number will be swarf. Steve

Logic says that a 3" lift should have had +3" hoses or more. Steve

The flapper will not run the pump unless the engine is running or cranking i.e. the flap is being opened by the air flow. You can take of the pipe from the air filter at the air flow meter and move the flap with your finger. With ignition on you should hear the pump running particularly if you stick you head under the back end. If he twisted the rotor arm he may have displaced the balance weights which will completely screw things but this would have been after the non-start so is not the answer as to why it would not start then but could be a reason for it never starting again. Steve

Are you looking for someone to do beta testing? Steve

Can someone please supply me with matching fuel and spark tables for a 3.9. I only need pictures as I will have to type them in being a rebel using MSII. Have had a troll back through the thread and have found both but they came from different sources so am not confident they will sit well together. Also the spark table was quite extreme and I'm not sure I want to go that far out on a limb for my first run. Many thanks Steve

You would do well to find a pay and play site first and learn how to handle your vehicle. If you are on site with a club someone will be willing to ride out with you and teach you a little about how to do things. If you just go off green laning without these skills you not only stand a good chance of getting stuck but your attempts at getting out could do further damage to the lane/countryside. Steve

Somewhere back in the depths of this thread I'm sure I will find the definitive map files for a 3.9. Before I go searching for it/them I need to know if it will be compatible with MSII as I believe most before me have been using MSI or MSnS-extra. Ran my completed MS on the stim for the first time yesterday and all seems to be working fine. When I load up someone else's map does that set all the other parameters like sensor calibration etc or do I have to work through and set those separately? Thanks Steve

We have a Clark mast mount on the back of the 110 belonging to our RAYNET group. It looks primarily military and works very well. It is angle adjustable. Steve

I would estimate the ice in that link to be about 5 inches. Ice road truckers are getting scared when the ice is only 3 feet thick. Steve
