  1. Hi- I run an Atom G4+ on an old 6 cylinder Jag and run 3 injectors of 1 drive no problems . So you could run 3 each of drives 1 and 2 . run group fire injection .

    Lambda display

    Hi i have a small problem with displaying Lambda 1 on a digital graph . Ive connected an AEM-x via can and seems all good . I have not started the engine yet . I just want to display Lambda1 on a digital gauge but it seems to default read Average AFR . Even if i request Lambda 1 . On a Dial type gauge the dial needle displays the correct ( as you'd expect) open air reading and it shows two sets of digital readouts within the dial one at high Lambda and one at low AFR . How do i delete the AFR reading/parameter ?
  3. Hi Simon - I emailed sales earlier this week but got no reply . Can you check with them if they received it please ?. Let me know if not and ill resend . Thanks .
  4. Cool- Thanks Adam .

    Jag fuel map

    Hi ive fitted a Link Atom G4+ to an old Jaguar . Can anyone suggest a fuel map as a starting point for getting it running . Ill be using traditional tune and its got 500cc injectors . A starting point for a master fuel number would help also . Its a 6 cylinder 4.2 litre .. Maybe 220 hp std . Thanks .

    Unlock code

    Hi- i bought a Link Atom g4+ off TM about a year ago - i dont think it was ever powered up . How do i go about getting the unlock code for when i do power it up ? Thanks - Ken
  7. Hi- is the Pertronix dizzy a ready to run type like an MSD one or does it require an amplifier box such as a MSD6AL or equivalent ? If it requires an amplifier box then honestly it is so easy to set up the ignition side on the Atom . I have used an Atom G4+ on my Dodge V8 running a dizzy and can say im very happy with it . Certainly the ignition map is easier to set up and tune than the fuel IMO .

    AEM - can

    Just to confirm - Via can -i want to use the AN channels for other sensors ?

    AEM - can

    Hi - can you tell me if the AEM x series 30-0300 wideband is able to connect to the Link G4+ via can ? . Its advertised as having a can output but just checking - Plus how do you rate them ? - Thanks - Ken .
  10. Simon - One more crazy idea - Could you wire two injector drives together ( say 1 and 3 ) and have enough power to drive 3 low impedance in series . And do this twice for a six cylinder and run it in group fire ?
  11. In 2014 Simon replied to a question about running a 6 cyl with a Atom G4+ - "You have to run group. If you have high impedance injectors then wire in two groups of three (one drive per bank will be fine) If low impedance then you will need to do it using all 4 drives drive 1 and 3 firing one bank and 2 and 4 the other." Can Simon please clarify how he would wire up the low impedance injectors using all 4 drives please ?
  12. Ok - Just thought i could take advantage of all the cheap evo or nissan injectors for sale which are low impedance . Just bought a Atom G4+ for a 6 cylinder project and looking at options - From your comments - injectors wired in series is probably not an option . Ta anyway .
  13. So i havnt bought any yet . Just thought id run this by you to see if its a possibility ? Yes 3 in series . How would the math work if they were 2-3 or 4 ohms ?
  14. Hi- i know youve been asked before but cant find any answers . On a 6 cylinder can i wire up 3 low impedance injectors in series and run them off 1 injector drive ? Have 3 injectors on drives 1 and 2 and run group fire ?? Thanks - Ken
  15. Hi- Could it be as you are off throttle pulling high vacuum you are accessing points in your fuel map that are lean ? Then as you go to full throttle again you get a resultant lean spike ? Just a thought .
  16. Hi- Wondering if youve got this running ? Would you mind posting your fuel and ignition maps so i can compare please ?
  17. Hi - I did this to the MSD distributor on my Dodge V8 . I timed the dizzy as you would ordinarily- found the no1 tooth and ground off the remaining 7 . The MSD dizzy had the facility to lock it - so no centrifugal advance comes into play . Also it is a VR type pickup . When i timed the gap on the 60-2 wheel i used - it was approx 90 degrees away from when TDC occurred at the dizzy . I had no issues with phasing of the gaps so cant say either way about that .
  18. Here it is . It was hard to know what to give it in the range it cruises in . On old school carb and dizzy engines vacuum advance comes into play - But i run an overdrive auto so it cruises at quiet low revs even at 100-110 kph and so i didnt want to give it 40 odd degrees at 1500-2000 rpm . Anyway it is what it is - Im sure not perfect - but it runs great .
  19. Hi- I have a turbo BB mopar and can give you the ignition map for that if you wish . The timing is no doubt a little conservative as i tuned the engine myself without going on a dyno . Its also low compression but as long as the comp youre running is not to high it will certainly get you running and be fine to drive on . Let me know if you want me to post it up for you - Ken .
  20. Hi- An old saying is - An engine wants what it wants - . Perhaps make it richer in the areas where you feel this noticeable bucking. To me this is a sign of running lean . With your cams you can get intake reversion and all sorts of weird pressure waves happening that can effect smooth running . Especially at that point of light throttle and low/medium engine speed . Dont be stuck on A/F targets at this particular problem area - Try it at 0.9 and see how it runs .
  21. Hi - Im sure no amount of bad cam timing or ignition timiming or stuck valves or any other mechanical issue is going to make an engine idle at 6psi positive pressure - No way - no how . Hook up a mechanical vacuum gauge to confirm . I think it will be a map sensor or electrical issue over mechanical .
  22. Hi Adam - I dont seem to have that option on my idle control page . No park/neutral step . Is it on the Atom G4+ ? . I have not up dated the firmware in a while although it is mentioned in the link help file . I doubled checked my settings on the anti stall gain and i have increased those - From 15 to 25 . So ill try that too .
  23. Ok ta for that . Also is there any way to speed up its action . Even with all gains maxed it is painfully slow to open and react when say putting the car into gear ( Auto ) . You can watch it count open in tenths of a percent on the lap top . How fast do the Bosch solenoids react ? Is it the valve thats slow ? Or just the way the Link controls it ( Its set to 200HZ ) Are there faster reacting ones on the market that the Link can control faster ?

    ISC solenoid

    Hi- with the Atom G4+ - When the ecu powers up but the engine is not cranking or running the isc solenoid ( bosch 3 wire ) stays closed . Is this right ? It only starts to open when cranking . Can i get it to open to its set point in the - idle base position table - before closed loop control takes effect ??
