10k resistor mod for the win!! Jumpered between TSEL and VRIN on the board. Lucky I put headers there to make it easy during the build ;-) All good right through the rev range now. Time for some tuning. Then the Idle valve install. And the new fuel rails. And the new injectors. Oh, and the LS1 coil pack install. Might leave the tuning to a simple get it OK attempt for the moment... :-D Thanks for everyone's advice and assistance!! Trav.

Between kids, sport, weather and housework I didn't manage to get to the wreckers over the weekend. I did manage to sneak in an indoor job and have put the resistor pack back into line with the injectors which should remove them from most of the noise equation just in case. For no reason I removed the pack from the wiring loom when I built it up. Having read a lot more now I realise I should have just left it in place. PWM is a noisy bugger. Adjusting the GAP on the distributor I did notice there is a very small (0.003") play on the drive - one side had a clearance of 0.006" but when I rotated it through each cylinder position the opposite side had only 0.003" air gap. Maybe that's what the manual refers to when it states "Not less than 0.006". So I've adjusted it to have 0.006" (the recommended gap) at the closest point resulting in 0.009 on the other side. She revs higher now (to 3100rpm'ish) but not much better than I had before (about 2400rpm). I might go out to a 0.010" gap at the closest point but will do the in-line 10k resistor next unless that gap gets it to 5500rpm. Cheers, Trav.

On the plugs Adam - wasn't aware, do you have the detail?

I'm running a BIP with the coil and distributor. When I pulled apart the Lucas ignition box it had a GM module in it! Dizzy has the vacuum advance removed and the mechanical welded shut so all good there. Yeah the LS1 are logic level coils with the igniter integral. Should tidy things up very nicely. Pick-a-part on the weekend and I'm grabbing everything you've mentioned minus the IAT - I got one from DIYAuto as the old setup didn't have any (it was fuelled by an old, old Motec ECU. hand soldered, with POT adjustment). I tried adjusting the Air Gap last night and it got worse so tonight will be the in-line resistor option to see if that resolves it. If not that then I'll get the trigger wheel cut (thanks Cheesy) and get the COP in place.

I've got a set of LS1 coils and am casting up some mounts for those on the weekend. Soon I'll have a trigger wheel and I'll go grab a crank VR from Nick-a-part (Ford Falcon in origin most likely). So while I'm savouring the challenges introduced by Lucas Lord of Darkness and his VR sensor's capabilities, I hope to have some shiny new wasted COP ignition bits ready sooner rather than later anyways :-)

Might be a cheeky question but does anyone have a CAD drawing they can share of the rover 36-1 trigger wheel? Shipping of those things to downunder is horendous given the cost of the item and I can get one cut on the waterjet at school, if I had the dimensions...

I'm not getting resets and the regularity of the tooth logs makes me think it is mechanical in nature. I'm going to try expanding the gap a bit to see if that helps. I've also been advised to try a 10k resistor in line with the sensor wire which I assume is to reduce the voltage back to the ECU. From my understanding the closer the gap the higher the voltage at higher RPM so this would bring it back into a more 'believable' range.

It won't let me upload the MSL or CSV logs...no luck with zip files either.

Sorry for the wait on reply - MS2V3. O, and I'm wondering how to physically mount them - electronics I'm good with.

The fuel table pic above was the wrong one in MLV (showing 16x16 on a map that was 12x12 - table was ok, it's just the display that is off). She runs OK now, up to about 2500rpm. Looking at the logs it looks like something mechanical is going wrong at that point. The tooth log and composite logs show a regular issue as RPMs increase. Might be a tooth on the VR sensor (35DM8 dizzy) a bit off maybe? Does anyone know what the recommended air gap in the dirstributor should be? I can only find reference to "no less than 6 thou" but can't find an actual recommended figure anywhere. How does one upload log files?? Trav.

Hi, I've had a look around here as well as a general search on the interwebs and haven't been able to find details on how / if people have mounted LS1/2 type coil packs in a Range Rover. Anyone done it? Pics? Cheers, Trav.

Quoting a quote here so not sure how it will look, but here goes... FridgeFreezer, on 10 Sept 2007 - 7:37 PM, said: There's plenty of reference on this thread and others to finding msq files all over the place. My Google Foo is strong and yet I cannot find any of the little buggers. Everywhere I look they are old, expired or deleted links. Would be great to have an updated list of files here on the forum somewhere to centralise the known good msq library. Mean time, I have put together my own VE and Ignition tables from the various screenshots herein and have got her started but would be nice to have seen an MSQ from scratch. Cheers, Trav.

Howdy, My injectors are low-z so if run at 100% current will heat up and die. They are the original injectors from a 3.5lt (circa '86) which were original in the car. You can run high-z injectors at 100% current (and that oddly specific time of 25.6ms) but not low-z. Settings I have tuned a little are now 30% current limit and 1.3ms time threshold. It is a 'fake' peak and hold setup - PWM so some initial full current (the 1.0 or in my case now 1.3ms) followed by 30% of current at 66us intervals means they don't heat up and the current is enough to hold the injector open for the required time. Mine still run's oddly but I have just opened a log in MLV and then opened up the tune file in MLV as well and it is showing a 16x16 VE table. In the tune file it is set up as 12x12. There are some odd values in there (circled in red) - can anyone comment, is this a bug in MLV or is my tune file corrupt somehow which is why I'm getting weird issues?? Cheers, Trav.

Thanks Nige, Waiting with baited breath and crappy running engine...although I made it idle nice ;-)

Howdy, I have a MS2 V3 newly minted and installed on my 4.6 with much gnashing of teeth over wiring and VR sensor shielding issues and general banging about never having done this before. The car is a little odd - '86 Rangie Vitesse originally (4.2 with the bigger valve heads), it had an old, hand soldered, Motec fuel only ECU on it which died (hence the Megasquirt). Threw a main cap through the side of the original block a few years back, now has a new 4.6lt short motor in it. EFI setup has the old 3.5l injectors, temp based air control valve thingy on the front of the block. After some VR signal shielding issues and a fuel pump wiring problem (which had killed the original ECU main board) she starts (yay!) Runs a little rough while warming up but pretty OK and I've tuned the idle now so it purrs like a very happy little kitten. Problem is as soon as I start to try and raise the revs it's all over the shop. Missing, bucking, kicking, panting. Generally made of fail. Attached are the MSQ and a start up log. (edit: I don't have permission to upload an MSL file??) Would appreciate some advice. Cheers, Trav. 2014-07-17_00.07.44 still running rough.msq
