We're getting there spent 7 hours trying to communicate with it Bought the full version of tuner studio £44 worth every penny was communicating in minutes still got a flat spot when cold and hunting but will sort that once we get it running right at operating temp Anybody know what A.F.R I shoud be running im not after out and out performance its just a laning and pay and play toy Also anybody got any ignition tables for lpg

Changed settings as you said there is no option for029v there is a 029c went for that still says theres a critical error it runs and ive got working guages won't let me download or burn to ecu On mates rolling road now on tuner studio ms working a dream

Thanks for your help now running on petrol and lpg

Update still not running on petrol been through schematics and injector pins are bridged inside ecu so that wasn't the cause Got it up to temperature running on lpg wue led goes out and rpms drop to around 900 led for throtle blinks when you hit throtle Noticed today that led for injectors lights when warm but ive still nothing coming out of injector pins on megasquirt is it software related and has this 990000% duty cycle got anything to do with it ?

Just had oscilloscope on it got +5volt -5volt pulses across pins 2&4 and nearly 6volt +- pulses across pins 5and 7 Where do i go next ? Thanks

Not changed any settings but laptop had s do when first plugged in and said something bad could happen can't remember what exactly so injector outputs bridged not a problem then Im away this week but will get oscilloscope on it Monday night and see what i get Thanks

It never had resistor pack for injectors mine is one of the last 3.5 s came with hotwire and ran two catalytic converters from new all injectors were reconditioned last year too

Fuel pump is running while cranking rpm showing around 200 when cranking everything is there to make it run if you short injectors to earth they click and it attempts to start on leftover fuel got no negative pulse coming out of Ecu injector pins and led not flashing on ecu

Got my lovely new megasquirt kit nigel (great bit of kit ) All installed on my 3.5 v8 but wont start on petrol fires straight up on lpg blos carb I have no negative pulse going to injectors and injector led doesnt flash on ecu I have live feed to injectors and fuel disconnected ecu and momenterally ground injector pins (32,33,34,35) to earth and you can here injectors click attempt to start and it runs briefly Checked tps calibration with nigel incase flood control was activating swoped vr sensor wiring round no spark and wont run on lpg and no rpm recorded on megatune after a sleepless nite last nite remembered that I had joined injector wires together before splitting into four for each bank so pins 32&33were briged bank a and pins 34&35 bridged bank b sorted that this morning and continuity checked with injectors unplugged no continuity so good there but still no injector pulse / led could i have damaged ecu by pins being bridged ? Checked pip signal on oscilloscope got a good 0v 12v square wave at ecu checked all wiring through again everything works as it should bar injector pulse only other possibility I thought of was my megatune looks different to nigels and had a bit of a do with itself when i first connted it to ecu could i have wiped program or something the other two leds are working as they should d15 comes on on cold start and d16 flashes when throttle is buried attached a pic of my megatune on petrol cranking no start if it gives anyone a clue what ive done wrong any help greatly appreciated

Tried vr wiring other way round no spark so that was ok put it back other way got spark and 100rpm on megatune rpm sensor when cranking but injectors and led still not getting pulse checked pip signal with oscilloscope got a good square 0v - 12v signal Disconnected megasquirt briged fuel pump relay out shorted injector pins at ecu end to ground momenterally whilst cranking and she runs breafly messed around with tps incase that was bringing flood control in but still no pulse

New problem now im afraid got my modified ecu back from nigel all tested and working pluged it into my motor and laptop Won't run i have spark so assuming vr wiring correct way round injectors have power but no pulse injector led is not flashing on ecu and megatune shows no rpm going to look at pip signal to ms tomorrow unless anyone can suggest anything else

THANKS FOR ALL YOUR HELP GOING TO SEND IT BACK TO NIGEL AND SEE WHAT CAN BE DONE

I could manage the pwm mod I think but then there's my other issues and the fact that i will have a lot more componants on the board than you is it going to cause a problem leaving them on also I allready have a transitor top right is this no needed on our installs To be honest if i cant get sombody to modify my ecu to what i need im going to have to bite the bullit and buy another one ready built with mods i need as its holding project up and i need to put paying jobs in its place the joys of being self employed im afraid Thanks for the picture it confirms that i was wrong to assume the kit i got was everything i needed

Heres the pics of my ecu please help ?

Right yes will be running edis pwm twin ignition tables for lpg and a a tach fix box all from nige Built ecu as per Megasquirt instructions fitted every component barr bip whatever it was and r57 fitted two jumpers for vr and tachselct ill get some pictures on tonight but board is basically full

Haha i need a huge magic wand not confident enough to start swoping and changing componants round do you have some contact details for your magician ? The kit as whole is awesome by the way There is a discrepancy in the build instructions with coil pack wiring a& b conections are back to front in description according to all the wiring diagrams and i do have coil pack release tags to bottom checked it several times and got a friend to double check c&d are fine so went with diagram will see when i get ecu sorted Thanks

The ecu was a self build nigels instructions are excellent for the install but never got any for the ecu build so dowloaded build manual and basically fitted everything but r57 and bip373 to be honest im at the end of my tether with building ecu with no help ( my own fault was hoping to gain a better understanding of how they work ) i just want to plug it in now and attempt to start it is there anyone on here that i can pay to do mods and put a base map on nigel has a guy that builds them for him but i never got chance to get his number Thanks for all your yet again

1The tacho was driven off distrutor negative pulse before (white/black wire) this is now connected to tach out on tacho fix box just don't know where tach in shoud connect surely one of pins at edis but which one 2 this will have to wait i did ask for switchable tables and theres no component spaces left on board apart from r57 3 yes i saw the bigger transistor and diode in build manual but i orderd pwm at same time as ecu i have no spare transistor slots on heatsink so was assuming it was up there nigel said they were pwm ready or maybe thats the ones he gets built 4 im running nigels vr setup from what i can gather from manual i have the jumpers right 5 r 57 is left blank according to manual 6 im on edis so that helps Thanks for your help dying to attemp firing the old girl up but never got base map for 3.5 v8 on my build cd has anyone got one ?

Hi I'm new to all this so please be gentle purchased a wonderful megasquirt kit from nigel with a diy ecu Im tantalisingly close to firing the beast up but want to sort a few issues before i plug it in can't seem to get hold of nigel at the moment so thought I would throw myself at your mercy 1 i have a tach fix box but unsure where I should connect the tach input to ? 2 i want to run switchable tables as will be running lpg does the ecu need a mod and which pin would triger the change presumably with +12volt feed from lpg switch ? 3 is ecu ready to run the pwm ? 4 i have jumpers fitted to tsel-vrout and tachselect-vr in is this all that's required 5 from what i can gather r57 is left blank on pcb 6 lastly i have a component left over (bip373) can't find any information on this at all
