To be honest as much as I'd like Phil to map it that wouldn't be in the spirit of the thread.
Everything I can do myself I will. Christ, I've come this far, so an attempt at mapping will be on the cards.

It's n/a so you can do a lot of it on the road in auto tune , if it's got a base map in with your inj size engine size etc it will generate an afr target map which you can compare to other tables from a quick google search . Mines turbo charged but I did all the part load stuff up to 100kpa with a couple of hours driving with the accel enrichment turned off

I have Ms1 in my rv8 powered Defender, and Ms2 in my rv8 powered Rover P6. The Defender used to be my daily, and the P6 is my daily now.
You won't regret the MS, yeah the learning curve can be steep and you will probably have a few frustrating patches here and there but overall it's all been plusses for me.
Better starting in all weathers
Better power
Better economy
Ability to hook up a laptop/phone/tablet and see what is going on in real-time.
Ability to datalog.
One thing would I would say is that its definitely worth investing in the full version of Tunerstudio. The autotune features are a godsend and well worth the cash alone.

The only faff is building the cold start table but registering the tuner studio will give you access to updates with auto tune features for cold start etc . The only thing you can't really do is final tune the ignition as you really need a Dyno to hold load and see where peak power is v ignition

Oooh, goody. More bits have arrived!!  One complete Chimaera-specific MS engine loom. Will need further tweaking to make work mind you, but apart from HT leads this is the last big thing needed to get a start up on the engine. Oh wait...  Should be an interesting weekend... |

I'm out of practice with keeping build threads up to date. My bad. Here's where we are at to date. So over the past few weeks I've been sneaking an hour here and there in the garage. For the most part, I have been pretty sensible with my approach to altering all the stuff I am doing with this ECU upgrade. As such, I have been sensible in testing the new loom rather than just routing it all in and hoping for the best. The joys of owning a convertible for this cannot be overstated...  Yup, just run the whole loom over the windscreen. That way, if you need to test things its pretty easy to access. In fairness, I needn't have worried. Shaun has done a phenomenal job with the loom. Every plug just sits where it needs to be, and for the coils I have enough stretch to get creative with where I want them to live. So much so that with the absence of a bracket to locate them on I just flopped them where the original dizzy was...  Instructions were a doddle to work from too. At worst, I'd say 3 Haynes spanners, lol. In fact, the whole kit seems so good that it was making the rest of the engine look shabby. Noticed the plenum is off? Yep...  Down to the unit for an afternoon of painty niceness..  Turned out nice too, i think. Only problem with that is..  The rocker covers and all the rest look curse word now. They will come off soon, along with some form of chrome / alloy PS reservoir. That thing is old, and the lines are weeping too. Its on the to do list! On the subject of to do lists actually, noticed that the pulleys are absent in the pictures?  In usual Overdrive style, any chance to turn a simple repair into an overblown project can and will be taken. What's the story with this you ask?  Aye. January blues took me on a different route to most of the populations sale purchase stuff. It was time to get a bit more technical in the Skunkworks. Stay tuned on that one. So that's a lot of waffle and diversions for an update on running a loom in. What we all want to know is, with the loom test fitted, did it work? OK, go on then.... Yup! |

The joys of having a garage under your bedroom is the sneaky hour you can grab mid week. Last night I decided to finish routing the loom through the bulkhead. All sorted, I popped the lower dash back in place and sized up where the ECU will sit. I think I can get it up behind the top dash panel now, which is a massive improvement over in front of wet feet where it lived before! After that it was time to pull the rocker covers off for a refurb. As with everything else on this car I was bracing for a shock. I was pleasantly surprised..  This is how they looked straight off the car, no cleaning at all!  The tops of the heads back up the story. Remember kids, frequent oil changes are not just an idea to make you buy oil... |

Good productive weekend. The loom, having been run through the car properly, is now being terminated to length and bits are being bolted up properly. Thats not to say things are moving fast. In an effort to make life easy some engine parts have been removed to allow better access. Parts that have since been given some attention..  I'm a sucker for black.  Shiny shiny. Whilst waiting on paint drying there was some more fannying around with the software, which I am pleased to say is now working as it should. there may or may not have been an earth missed that hampered progress, but the guts of the problem was down to a problematic USB to serial convertor. Bloody computers....  It was all going so well too, then I went to put the rockers on with new rubber gaskets. Was just about to bolt up the last side and i heard a "clink". This wont be good....  Yea, the little metal collar dropped out the gasket and fell into the guts of the head. I hope its magnetic.... |

Relax, I got this. It was ferrous so a mag pen (i love eBay) sorted it out. Had another wee hour last night. The amount of times I have had that transit boot for passing the loom through the bulkhead off is starting to become unreasonable. All in the name of a good install I suppose. Last night I had established that the Innovate WBL set up should probably not live in the engine bay, inches from a tubular manifold and directly under a bonnet vent. No biggie, except I had inadvertently plumbed the plug connecting the input for it to the megasquirt loom to be in the engine bay. Out it came, and I pulled the plug to sit inside the cabin. That was a forgivable mistake. What wasn't forgivable was reinstating the boot into the firewall, causing the usual fibreglass rash on my hand in the process, then realising that I had forgotten to run the lambda probe wire for the Innovate through the damn boot. Off we go again! Balls. So once I had ACTUALLY sorted the loom, I was able to throw the rockers on... the bay is starting to look pretty good now..  This picture greatly illustrates how poor the lighting is in my house garage. Here's one with a bit of flash..  Looking better. Still to do on the dress up is properly tidy the loom, and mount those coils! After that, its an oil change and deal with the power steering hoses (perished and weeping) then finally knock up some alloy pulleys and this side is done! On the inside I thought it prudent to verify that all this additional electronic hardware was going to be happy where I had routed it...  Again, curse word light, but the top panel for the dash does indeed cover the ECU in its new upper-dash home. I'm really glad about that as I was never happy with it living in the footwell. |

Spent a few hours trying to get the old girl running again with the laptop communicating through Tunerstudio and with the new loom routing in. For some reason the lump was far more reticent to fire up this time, and ran like a bag of burst buttholes when it did. Luckily, the software held some clues, and with fetlling a steady, if choppy, idle was achieved. More promising progress! Unfortunately this was achieved with over 20 degrees of advance thrown at it, so there is a fair chance I'm going to have to whip the crank pulley off again and dial the error out on the trigger wheel by rotating it (cue some tongue-out-the-side-of-the-mouth action as i try to determine what direction this needs to move in!!) To be honest pulling the crank off isn't going to be that much of a horror story. I will need to pull the collector off again because of this little dude..  I had assumed the wideband lambda sensor would just utilise one of the existing ports on the headers (exhaust manifolds)and as such carried on with things blissfully unaware that more monkey work was looming. A quick comparison of the removed sensor revealed this to be bogus:  Naw. So the bung that came with the Innovate would be put to good use. I'm happy enough because I was not too enamoured with the prospect of ignoring one bank on the AFR side of things, so the new port could be further down the collector picking up all the engines exhaust. The only issue as any Chimaera owner will attest to, is the whole exhaust needs to come off to allow enough wiggle room to pull the collector out. Again. Following a quick check to determine how much protrusion i would need (these wee things sit snug!)  ...and it was out with the welder....  Yes I did remember to drill a hole first. Bit of a shame this will hide down the guts of the engine bay, I'm starting to feel a bit happier about the presentation of my welding now. Anyway, finished article looks a bit like this:  Still to come, a bit of custom work on the rear ARB, new tires, a ruddy good clean, tune up and then its time to MOT it (I hope) |

You might want to cut that boss down if the sensor isn't sitting in the flow it won't read very well

I have done bud, trimmed a good 5mm off it before welding it on, then ground in a further crescent to make it flush to the collector. Should be bang on.

I thought the WB sensors don't live living too close - should be 1m from the closest exhaust valve IIRC?

They will easily be that far to be fair. The manifolds point to the front of the engine, and that collector has the sensor at the bottom of it.

Ah - that's answered that one  I remember something in the instructions for mine and when I looked, it was a lot further down than where a narrowband sensor would live on the engine I was going to use it. |

I wouldn't be surprised if they say that to help the longevity of the sensor...

I've found with my car that it's happier at around 13.5-13.8 afr idle With the little cluster of cells around the idle point with the same value in to keep it steady |
