  1. Thanks for the reply Simon So updated to the latest pclink software and flashed in the new firmware iac is sort of working lol the ecu is loosing track of where the Iac is.i got it to idle at target rpm then I tap the gas and it goes to 1600rpm and stays there for around 1.30 minutes then slowly over a minute comes back down to target rev it again and it stays high forever adjust max clamp till it comes back down and give it another stab and it locks high again adjust clamp well past the maximum amount of steps possible for a gm Iac and it comes down again but yet again as soon as I touch the gas it holds revs bad it's just a constant battle of it loosing losing its position .even after keying off and restarting it can't sort itself out The other thing is every update tge software is getting slower and slower the software is now so slow in win10 that I would nearly call it unusable the last version was ok after it started and sorted its shit out this version its slow selecting any menus takes ages going from one setting to the next as it is a long wait for anything to happen
  2. Hey guys finally getting to tuning this turbo 304 on g4+ storm and the Iac is not working as expected. At first it was happily clicking away at key on resetting itself but would always idle high upto 1500rpm it occasionally works and drops idle to target of 750rpm . then it would hang after a rev and take ages to drop if it dropped at all and now it doesn't even move when I key on .if I take it out of the throttlebody it just gives a brief hum at key on no longer makes any noise resetting itself. I can plug the Iac into my daily with factory Holden Delco ecu and it works fine its just like the link isn't supplying enough current to drive the stepper Have also tried a second iac with the same results It's wired as per instruction to aux 5 6 7 and 8
  3. Thanks mate I ran switched 12v to the relay in the back.she runs sort of all be it badly but I'm stuck till I have another pair of hands tomorrow to help crank it while I adjust the dizzy to get timing closer to correct .that's all I needed to confirm before bolting it all together for its final time.
  4. No it stopped and then spat out 3 or 4 sparks . Next issue fuel pump output positive switching won't trigger my relay and if I set it up negative switching and swap the other side of my relay to power my fuel pump runs when I turn the key off cause the link defaults the transistor to earth .the relay is in the rear where the battery is so I can't easily add switched ignition to the rear to stop it triggering with key off unless I run yet another wire How much current can the link output surely enough to trigger a relay coil ?
  5. Guess I'll fit the plugs and add fuel and see what happens thanks for your assistance
  6. Was out in the shed doing the trigger scope .I have not primed the fuel system yet so there's no fuel but I will turn it off to stop the injectors getting hot.heres the ecu information window with serial number and current firmware etc and the scope trace even the scope trace takes a while to show anything but shows 8 pulses plus 1 sync pulse .I'll uoad a video to YouTube shortly of the spark output video .it will probably run but I'm not keen to try with rogue sparks happening inside the distributor cap at random times lol
  7. this is where im at with the ecu setup iac is operational resets and parks on key on i havnt setup the diode power feed mod for iac yet dans cop car link.pclr
  8. thanks for the reply.its a new g4+ storm dual plug ecu i will get the serial number off it in the morning . i have the 4 earths run to 2 seperate locations about 2 inches apart on the front of the block the ignitor earth wire is earthed to the body on one strut tower bolt temporarily while i finish tidying up the mess and finalise placement of the ignitor and coil.
  9. Hey guys I'm just finishing off a wiring job that someone did a mare of a job on with housewiring in the mix and a lot of fail lol. ive fixed all the bodgy stuff and done some initial setup for the VT sequential distributor (brandnew)and link single channel ignitor ,injectors etc . Got spark via ignition test function all injectors wired in sequential mode some injectors click nicely when tested some sound like they are galloping instead of a steady tick. The big problem is when I crank the engine the spark is delayed for a second or so before it starts arcing to earth out of the coil lead and when I stop cranking and the engine stops moving the coil keeps sparking for a couple of seconds probably sparks at least 8 times while the crank isn't moving not ideal Thanks guys Any ideas Ps not my first link rodeo I've used a lot of them before with no issues on sr's and rb's and 1uzfe but first time on a 304 I normally tune the stock Delco ecus for boost hence the username
