If you bought the Megajolt box from TriggerWheel there should be a base map for a Rover V8 and a TR7 V8 included on a cd - if you don't have it I miht be able to dig it out somewhere

Maybe a silly question - but you did a Save/Write after the VE analysis ?

Flood clear is a feature of the 14CUX too

I'm using an Innovate MTX (which uses Bosch sensors), and have been pretty satisfied with it so far. Cheers Michael

I wouldn't put a hacksaw to the loom - why not reuse all the wiring and add a few extra for the ignition ? Phil Ringwood/Shaun makes a MSII that re-uses the wiring, if you don't wnat to fiddle with it yourself

Yes its a 1990 with 14CUX - before going full Megasquirt Ive run with an Electronic 123Ignition distributor - never thought it had a feed to the 14CUX - is that over the Coil it feed the ECU?

What car/model is it ? My RRC 1990 when running on 14CUX gets absolutely no input from the distributor ? Cheers Michael

No problem at all I just thought it could be nice to compare and poke around in well-working 3.9 V8 MSQ - even though I realise they'll never be 100% applicable from one engine setup to another.

I'm only a newbie, so bare with me, and my stupid questions. So if you ever need some advice on how to build coorporate databases, Ill tell you "Theres only really two possibilities regarding computers - it's called Bits, and it's either 0 or 1" ....

It's a Rover Pnp - I was just curious about how to check it

MS2 is a bit different - it looks like it doesn't cut of at a specific number of engine cycles - but it "tapers". So I tried to put in your percentage figures, and kept the current taper figures. Cold start was not better than before - but the car has been standing for a few days, so I need some more Cold starts to conclude on that - but warm start seems much better - it still takes some cranking, but now it keeps alive without the need to "blip" the throttle. Is there anything else I can look at to narrow down then problems - and maybe get rid of the "abundance" of cranking ?

It should be MS2 v3.57 - Phil Ringwood built it. Do you know what the "Bias Resistor Value" should be set at ?

Found the Ohm values for a Rover V8 coolant sensor in FridgeFreezers post (http://forums.lr4x4.com/index.php?showtopic=15317&page=11#entry234427) - but the Thermistor Table Tool also asks for a "Bias Resistor Value" - anyone knows what that figure is ? How can I check what sensor values are currently used ? Thak you Michael

I've been reading up a bit in the Mega Manual - and it sounds like my Cold/warm start problems could be due to wrong ASE settings - can someone running a rover V8 show me their ASE Percentage and ASE Taper values/Graphs ?

Thank you for warm welcome As mentioned Shaun helped me make a bood starting point, and the car drives very nicely indeed, and pulls like a train - compared to the old 14CUX anyway. The only minor problems I have now is with idle/startup. Cold startup: Bursts into life immediately, but needs two "blips" on the loud pedal to keep it going - after the two "blips" it idles nicely. Warm startup: Needs a fair bit of cranking before stumbling into start - after that it idles nicely. Thank you in advance for any hints - I'll answer your PM shortly Nigel Cheers Michael

Hi My name is Michael, and I'm from Denmark - so sorry about my weird English I have a Range Rover Classic, with a new Turner Engineering 3.9 V8 installed. It has gasflowed performance heads, a H180 Sports torque camshaft, and stainless steel headers and 3" exchaust system - all brand new. It's a non-cat 1990, so in order to see whats happening I've put on an Innovate LC1 wideband lamba connected to a Innovate MTX-L gauge. I couldnt quite get it running properly on the old 14CUX, so I took the plunge and went all in with a MS2 v3.57 - but as I'm not experienced in engine control systems, I thought it might be wise to get a "kit", so I bought a Rover V8 Plug-N-Play kit from Mr Ringwood, which uses all the exisiting wiring regarding injectors, Water temp, TPS etc. Afterwards I've read about Nigels excellent brackets and intake conversion bits, and he's been very helpful in sending them to Denmark. It goes like stink (in a good way:), but after having read many of your interesting threads, I'm worried that my ignition map might be a bit too "enthustiastic" The map was supplied by Shaun/Phil - but as far as I can read from Nigels advice, its not wise to go beyond 34 degrees on 3.9 - please see below:

Have you checked the stepper/IAC is fully closing - the howling could be due to a faulty stepper motor - or it's just not fully closing ? Have a nice day Michael
