Hi Thanks for all your help, even with changed name (.log .txt) i cant seem to upload it even as a zip file i am away for the next few days now (off to lemans )but will still be checking the forum and i can try and email it to anyone if they pm me there email address! Dave a spark map would be amazing! thanks again! Reuben

Hi all, no more luck today but i have got a datalog, unfortunatly i can work out how to post it, its an msl and the forum says i dont have permission to upload this type of file? i feel more stupid each time i attempt anything at the moment! Cheers Reuben

One step forwards two steps back... cant get it to idle properly on 8 anymore, all 8 manifolds are getting hot but the right bank much hotter than the left very lumpy again and generally sounding a bit rubbish i tried it on alpha_n which i believe is just using the tps and it wasn't any better. to me the map thing seems a bit of a vicious cycle ie when the engine is running badly its not producing much vacuum so gives an odd figure to the sensor thus not helping it to run any better and if anything worse Dave, as far as i can tell in speed density the %load is just map but could be completely wrong! when you say on a base map you would use steps between 20kpa and 100kpa with 5 point steps around the idle i am a little confused as to what you mean have you got any examples? regarding the ignition map have yo got any maps showing the bins around this or is there likely to be one on here? i though it seemed a little aggressive around the bottom end too when i had it running best it was fixed at 9 i am not particularly worried about it running perfectly just well and on 8 i bought into megasquirt fully expecting to have to have it setup by somebody who actually knows what they are doing! i was just hoping to have it running well enough to maybe drive it to wherever! and also not wasting expensive time at a rolling road to actually get it running on all cylinders consistently, it seems at the moment the more i read and play with megasquirt and tuner studio the less i understand it although thats almost certainly down to my brain getting fried by it! everyone's help is gratefully received! i will post up some log files when i get some hopefully tommorow! Thanks again Reuben

TPS is calibrated, i do actually have a second sensor for barometric correction but i might try and see if it works better by turning the other sensor off, i am pretty sure the odd load reading is caused by the vacuum setting though maybe its best to try and recalibrate that! Cheers Reuben

Dave, its a 36-1, i don't think its getting any resets, Had a good bit of progress tonight as i actually had it going on 8! i did this by changing the timing to static 9degrees (to check the timing again) and then changing the first few columns of the fuel table to one fixed value (i chose 20) as it seemed to be a decent idle value, at this point i noticed that the engine actually idles around 70-80% load! I think this maybe the problem? is there anyway to recalibrate the sensor to make it more appropriate it seems to be 45-50kpa at idle. I have attatched the msq file now i have changed the map back on the fuel table, i dont know if the fuel table seems a bit rich and the spark table a bit much as it seemed to idle nicely at 9deg advance and 20 on the fuel table! Cheers Reuben 90_new.msq

Dave, connected to a bung with a hole in it, seeing 100kpa before starting goes down to around 50 at idle which i get isnt low enough! any idea what i should be seeing? i cant find an obvious air leak anywhere, is there any gain to be had from moving the map pipe around?

MAP pipe is definitely connected, when you say to the wrong place i have it comping from the bottom of the plenum in one of the 3 holes in the side (ie where the brake vacuum hose is connected too, i cant find any leaks in the hose itself, its running a non standard cam (whatever a JE dakar came with?) dont know how much that would affect the idle vacuum? cheers Reuben

Ok will get on with going through the wiring again later gave it a check over, all the injectors have a pulse with a noid light still running badly on 4/5, i will give the test mode thing a go, the only thing i did notice was that the engine does not make much vacuum at all at tickover and was wondering whether this mite be caused by/causing the problem as i know the vaccum affects the %load read by the ecu?

Nige, no i dont think it has, i was probably kidding myself when i thought it was as was so happy just to have the thing running however briefly/badly! FF It is a new install yes i have been over the wiring two or three times but will go over it again later just to be sure! cheers Reuben

Hi Guys thanks for the replies the plugs are brand new, compression is 165psi give or take 5 psi on all cylinders, i have got one of the led light injector checkers on order so will try that tommorow, the injectors where bought as reconditioned so i hope they are ok the ms2 is an extra efi (phil ringwood) one firing a pair of ford gen2 coil packs. i guess the main thing to check now ie the biggest unknown is the injectors? Reuben

Hi I have read through some of the other posts on here such as the basics and the "so you have got you ms running" thread and am still having issues I have a JE 4.2 converted to a hotwire top end with a ms2 ecu i have got to the point it "starts" but when it does run its only on four maybe 5 if i am lucky! the 3 that don't run are the rearmost three on the left bank. as far as i can tell it is timed up, seems to have a spark on all 8 and so far as i can tell has fuel getting to all 8 did a compression test and all 8 are roughly the same. i think it is running too rich but if anyone has any ideas as to what else to check or what i might be doing wrong please let me know as i am running out of ideas! Cheers Reuben

ahh yeh very valid point i am in the hampshire area! thanks Reuben

Hi guys, where do you get your galving work done? thanks Reuben

is that the same lt85 box as was used in landys or has it been modded over time? are the doors land rover compatible as they look like a good defender replacement!

Hi guys was wondering if anyone could help/ knows what i have done wrong I have very recently swapped the engine in my 90 from a 3.5 twin carb to a 3.9 hotwire efi got it started and running fine. today i changed the plugs, leads, dizzy cap and rotor arm and now it will not start for love nor money, i changed the dizzy cap and rotor arm back and still nothing, it seems to crank about 5 times and bog down and then crank another few times and bog down again. Any ideas what this could be? Cheers Reuben
