Mr2@villela Posted September 30, 2016 Report Share Posted September 30, 2016 sorry guys I'm new in this forum and I have a problem with my car.first of all nice to meet all of you and here are the things I'm curious about.vehicle: 1991 Toyota mr2 swapped with a gen4 3sgte (caldina)had the car protuned back in spring of 2016 with mods listedmodsengine block and head stock, fuel stock 560cc, bolt onsspearco intercooler, gt3076r turbo, Racerx exhaust manifold & downpipe and external tial wastegate 38mm, just intake come, ems exhaust and atom g4+ link ecu.. Car ran great then a problem occurred. Blew piston 2 ring and car ran like shit. I have built a new engine for the car that I have finished and here are the specsbottom block 86.5mm wiseco pistons, eagle rods, arp main studs, arp head studs, new bearingshead stock intake valve and exhaust valves, 264 Brian crower exhaust and intake cam (w/ trigger), Engle springs and new seals.fuel injector dynamic 1000cc, 450 walboro e85 fuel pump with e85 lines.i have installed everything just the way the car is but the car doesn't turn over. Just cranks and cranks and like a misfire pop. The car has fuel and it also has spark so my main concern is the cam position sensor. The Brian crower camshaft can be a problem cause of the trigger? Or can it be a problem from wiring? Sensor is good. help also need a diagram of the atom to find out where the cam trigger is Quote Link to comment Share on other sites More sharing options...
Scott Posted October 3, 2016 Report Share Posted October 3, 2016 Welcome to the forum.In PCLink you can look at the Triggers/Limits tab of the Runtime values Window to see if you get the Trig 1 and Trig 2 status turning ok while cranking.The next step after that will be to use an oscilloscope to see what the trigger patterns look like at the Trig 1 and Trig 2 pins of the ECU. Here is the G4+ Atom pinout diagram:Scott Quote Link to comment Share on other sites More sharing options...

Brad Burnett Posted November 13, 2019 Report Share Posted November 13, 2019 @Mr2@villela 1: Did you resync/verify the ignition timing after all was reassembled? 2: Did you make any adjustments for the double capacity fuel system? Quote Link to comment Share on other sites More sharing options...
