Mr Noisy

Ah ha, found the 'open loop' settings and changed EGO limit to 100kpa

Thankyou for that explanation geek Ok I will do a few 15 minute logs and keep an eye on what MLV is up to. Regards the hardness setting in MLV, Nige told me about it the other day but I cannot find it! what am I missing?? Also yes regards the IAT, last night it was about 55F when driving but raising to 66F and no doubt more eventually when sat at the lights etc. I have tubular headers and nige's IAT adaptor MAF replaced thingy, which is right above bank 1 header! I have some heat insulation matting that I was using on my civic a few years back, will wrap the tube and see. Have also changed to degrees C in MT so that I actually understand the temp figures!!! Regards the EGO correction at high MAP, I think you mentioned that yesterday? I did have a look for it in the settings but couldn't decipher where the setting was located. Any more insight please?! And finally regards the wiring, urm, sorry yeah I just get keen sometimes!

Well, progress! Seems the key problem was not having set the AFR table. I am now using AFR target aswell, but yesterday I did not understand that MLV uses the AFR table to base it's tuning. The standard WB AFR table in MT was some kinda crazy figures, which is what I was getting on my AFR gauge. SO, set up an AFR table as per one that Bowie had developed (thankyou Bowie) and tried again. Even just on base map with target AFR it was doing a good job of leaning out to 14.7 on light cruise. Had to go to Preston tonight to pick up a viscous fan (£10 fan, £20 fuel lol ) so it had a good chance to datalog. Ran a log there for around 30-40 minutes, analysed, logged again, analysed, so now I'm on VE table 3 and it drives beautifully, SO MUCH POWER! AFR gauge is showing heathy results, 12:1 ish idle, 14.7 light cruise, 13.5:1 motorway cruise up to around 12:1 depending on how heavy the foot gets. Still learning, but can really feel the VE table coming along. It is impossibly smooth and powerful, compared to Hotwire and dizzy at least. Managed 85mph in it whereas before 70 was a struggle. No complaints whatsoever tonight, great results from a great drive out. Will work at it more because the second analyse still altered 75% of the table, the largest change being 12 points. Things I want to look at (I think) are leaning out the cruise more or maybe even building a map for motorway use, and need to improve my all rounder map further, obviously idle work will then be required because currently hot start takes a little while to stabilise! Also that tacho isn't working, but haven't had chance to probe the ECU output yet! Thanks for your help today chaps, as far as i know it has been a positive day today! Cheers

Thankyou for the tips bbc! Will work through it bit by bit, digesting the information and trying it out. Will double check my settings and have another go at things this evening

Thanks guys, will have a look into it. I have been reading lots but can't find any info on the MLV AFR settings part. For instance, WB AFR bins1 looks like a crazy table!

Oh and did I mention: Megasquirt SnE is f*cking incredible! It has turned my land rover into a sports car! Va va vooooom! (Now please help me make it work properly!)

Also should I have acceleration enrichment turned off when logging? I read that Phil Tobin recommends to keep AE and EGO correction both on when logging, using the car exactly as normal. I also wonder what exactly I should use as a switch point for the WB, and whether I should set up target tables is megatune BEFORE tuning. Tough cookie this one

I noticed that I did NOT "open msq" after I opened the datalog in MLV, but I assumed that it had automatically found it because the VE and spark table it had opened were looking believeable! Will have to check this!!

Anyway gennulmen! Has been a bit quiet on here past few days, basically over the weekend car has become drive able. Saturday was a late finish again, so Sunday I did some driving! Carried out a couple of datalogs on NB, and in fairness the map improved when analysed in MLV. Better power midrange and the idle was affected, so I knew changes were being made. I then loaded nige's base map again and set about wiring up my Wideband. Firstly, must say I like it! Much better than guessing what the AFR is!! Think I will look at drilling a hole in the floor etc so that I can run Wideband permanently but keep the controller inside. Going to take further advice on this but target AFR is a bonus. Anyway. So I went out for a 20 minute datalog, tried to cover all aspects. Car was basically rich (I have a WB gauge also) running around 8:1 at idle, 10:1 under power and around 13:1 on cruise. MLV made a lot of changes the first time it analysed, and then I had around 12.5:1 under power, a slightly hunting idle BUT on cruise gauge showed about 19:1 and overrun in the late 20s! Crimes I thought, datalog again for 5 minutes and MLV richened slightly, but still very lean on cruising. I reloaded the Nige map and thought I better consult the panel. One thing I am struggling to research is the AFR bins thing on MLV. I have got WB AFR bins1, WB AFR bins2 and default narrowband. Both WB bins looked super rich whereas the default NB table looked ideal, so I chose that both times before analysing. Could this be where I have gone wrong? Have I even gone wrong?? Idle needed retuning but it drove well after just an hour of logging. Hmmm

Yep that's kinda correct, because 4 cylinder has less coil wires and uses same plug there is a CTO on the unit but "I'm pretty sure" it's got an IDM aswell!

Hi fridge Tomorrow I'm going to have to measure the output from the d37 plug. It's an aftermarket tacho that previously was driven from the coil, but yeah I will need a 12v signal. Will have to meter it and see what it looks like, if anything! Thanks

Oh yeah and my tacho doesn't work Have set tacho out to JS0 and connected to spare1 but no go Any ideas please?!

It drives!!!! And rather well too. Flat spot cleared quickly. Viscous fan has seized, hoping it will free up, must have been sat for too long. Maybe it was the wrong way up, I have seen fans that must be stored on way up only. Anyway, other than that, basically ok! What to you mean WTF that disco come from?! And yeah VERY lucky to have an awesome workshop available!!

Phew! First time that has been on since 1st November, and it hasn't left the garage either!! Out for a shakedown drive tonight and then hopefully it will be dry tomorrow so we can go data logging!! Got a bad flat spot when I blip it up from tickover, hoping to sort that out rather quickly!! Cheers

I still reckon DTI is the best option, but a spark plug threaded bolt would be easy also, I guess it would work for all engines be used you just find the centre point between the two marks either side of guesstimate TDC.

Are all pistons the same on 9.35:1 RV8s? I used a DTI to help find TDC and im pretty sure that maximum piston height was achieved between 3* BTDC and 3* ATDC, this was the same as the pulley wheel marks on my 3.5 so we knew that the pulley was right, but on the 4.6 obvs you just find the centre point

Well, basically it has taken approximately 12 hours overall to go from this: To this: Hometime now, up at 8am

In a lorry on a bunk maybe it is too sleazy, but in a land rover on an adventure I'm thinking it'll be ok!

Yep, (honestly) got a bulk buy on red down at the wholesaler, so have about 6x 30m rolls of red and a few black. Making very sure to label each wire at every step Just thought of a genius plan that I will wire in tonight! Going to fit red "cockpit" lamps, with a changeover switch to switch between white and red lighting BUT it will be a DP switch wired accordingly so when switching to red it will kill the dashboard illumination! I know it is wrong that I am excited by wiring and lighting, but hey, it's my vice...

Tonight's work done! Basically ran more wires, rearward for work lights and LED beacons, forwards for LED beacons, left side of the dash for map light, roof lining for interior light (upgrade) and right side of dash for CB, then separated and bunched all the earths, and split the loom for fuse board, relay board, switch board, then added any wires running between these locations. Nige's cable tie technique has got me hooked, so neat!!! Loom is growing: More Land Rover repellant illegal neat wiring: And fitted MOAR carling switches arrive tomorrow and that switchboard will see some good progress methinks! Cheers!

Not a bad idea!

Connected my laptop today to check the ignition timing. Well, laptop says it should be 11.8 degrees ish at tickover. Fancy timing light says its 24 degrees, wtf??! Knocked the trim angle back 12 degrees and its gone way ATDC on the pulley, wtf?!?!?!?! It's taken me all day to realise that it's wasted spark, so it fires twice, hence the timing light gives it double the advance! It i set my timing light to TIMING (where it doesn't work out the advance for you) it lines up with 12 degrees on the pulley, so it's bang on. Phew, had me going there!

Feel like a right nob, it's wasted spark so sparks twice. I'm showing 24 degrees advance on my fancy timing light, but sparks twice so it's actually 12 degrees, and should be 11.8 Turns out its bang on, lol

Im having similar trouble, except I'm about 12 degrees out!!! Will look into it
