I bumped up the filtering to 2. Confirmed all plugs were good and ran it. Here is a scope as well as a log of the same conditions. running_rough_log.llg trigger scope 1.llg

This is the factory unit. I'll bump up the filter and then check out that wiring.

Sure. I'll create one today. Here's is one that I made a few weeks ago while chasing this same issue. 5ace1f0d4f101_TriggerScopeLog2018-04-11104250am.llg

Adam, Those changes actually got it running! it still defiitely seems to be misfiring.. hard, but it stays running. I can't really figure out why it would be misfiring.. with a test, all coils and injectors are firing. More fuel? Here's a log. running_rough_log.llg

Much appreciated Adam. I'll try this out.

Thanks for this. This is my first attempt at tuning so I'm still learning a lot. I'm going to apply everything you've said and see what happens.

I previously had an issue where I could not get one of my injectors to fire... ( see here -> http://forums.linkecu.com/topic/8319-st185-pnp-injector-3-not-firing/?tab=comments#comment-55843 ). I swapped out to another ecu, solving that problem but now I'm running into an issue where I absolutely cannot get the car to run correctly. It runs for a few moments, very, VERY roughly.. as if it's misfiring, and then dies. If I give it any throttle, it'll run for a few moments more. I would also like to mention that when I set base timing, I was dead on 0 for trigger offset at 10BTDC. I've change the trigger offset by 360 because I was advised this was necessary to get the car to run with these smart coils. The injectors are Bosch Ev14. Part #0 280 158 040. I'm running genuine Toyota 1zz smart coils. I've verified no vacuum leaks. I've verified all coils fire via an ignition test I've verified all injectors fire via an ignition test. I have deleted my OEM injector resistor packs by tying all wires to that plug together ( this seems to be the way to do this. ) Compression test yields 180psi across all four and fuel is in the rail. Below is my map. I'm really looking for some insight here as I am truly struggling to get this car running. I really appreciate any assistance. Thanks in advance. Daniel_map_final.pclr

Weird! It definitely did fire but I'll make that change and swap anything from 6 and then get back to you with results.

I tried that, with no luck unfortunately. Scott from Link US advised me to use inj4 as inj 3 and inj5 as inj 4. Fired right up. So I guess I'll just go that route.

This is brand new. Surely I should be able to use inj5 to drive my third injector?

Yeah I actually test fired the third injector with wiring for inj1,2,4 and 5. I also tried wiring for inj 3 on the other injectors and it did nothing.

Where exactly is that setting? Having a bit of trouble finding it. I 1000% thought of that but couldn't find the settings anywhere.

Thanks, I'm pretty sure it's not working. I'll see if one of the Link guys have any weight before I do that. That's a lot of down time...

Hey again folks. I'm having issues getting injector 3 to fire. I've swapped around plugs from the other injectors and they are able to fire injector 3 ( this is done internally using an injector test ). I am able to assign injector 5 as an injector and get it to fire the third injector, however. Injector 3 is getting batt voltage with key on and I've traced the wiring back to the ecu and have determined that for some reason, the ecu isn't grounding out the injector when tested. There are no breaks in connection. Am I able to just use inj 5 to pulse my third injector? And if so, what would be the best way to go about that? Thanks!

And she runs. Thanks to all who helped! Much appreciated.

So I was able to get all coils to fire by fixing the wiring ( guess you can't trust prefabbed wiring ).. Now I'm having issues getting the car to run.. she fires... but that's it. Here's a log and my cal. Any insight? Log-multiple cough.llg Daniel_ev14_1zz_edit_1.pclr

Okay thanks for that clarification! I'll make those changes once I'm back at the shop tomorrow and update you guys! Really appreciate the help.

Here's another thing I have a discrepancy with. In the help section for the ignition expansion connector for my ecu, this is what I see. (first image ). What exactly is the bottom row of text stating? Ignition 1 goes to 1, Ignition 2 goes to 2, ignition 4 goes to pin 3 and ignition 3 goes to pin 4? I don't think this would explain why Cylinder 1 won't fire and that coil keeps getting hot but this could be a start. I will note, that coils 2,3 and 4 all fire when I perform an ignition test. The second image is whats printed on my board and that's how each cylinder's IGT is wired.

To give some insight as to how my coils are wired - Each coil has it's IGT going to the ignition expansion on the board. 1 to 1, 2 to 2, etc. The power for each coil is going to the OEM igniter connector ( pin 3 below ) There is a wiring bridging from pin 2 to pin 4.. which I'm assuming is for the tachometer. What confuses me is that the 20th pin on ECU plug B that's talked about below is also considered Ign1. But... there's an Ign1 on the ignition expansion and that's where my #1 coil's trigger is wired to. The coils are commonly grounded on the head. ( 1 White/Red to ECU plug B 3rd spot (IBF)2 White/White to ECU plug B 20th spot (IGT)3 Black/Red to Ignition Main Relay (12+)4 Black/Black to Tachometer5 Black/White to Ignition coil and check connector (Diagnostic port) ) Additionally through an ignition test, I've discovered that the first coil will not fire.

I've never done a trigger scope so please bear with me if I did this incorrectly. Trigger Scope Log 2018-04-11 10;29;57 am.llg Apologies, I believe I did in fact do the first triggerscope incorrectly. Here's a corrected one. Trigger Scope Log 2018-04-11 10;42;50 am.llg

Hi, I'm having some issues getting my car running here and I was curious as to if any of you guys would have any insight. I was told to do a flat 2ms dwell for the coils as they typically don't like more than 2ms or they'll get too hot ( already killed my #1 coil multiple times - this is the only coil that gets hot. ) The COP harness I have has a common ground on the head, common power wired up to an ecu switched power. Coils are fired via the 4 pin ignition expansion connection on the ecu board. There is also a wiere ( I'm assuming a trigger ) going into the stock Igniter plug at one pin and another wire looped from one of those pins to another. This was a pnp kit purchased for this specific application. Additionally I'm having some issues with settings for these Bosch EV14 1000cc Injectors. No deadtime values or anything came with them. I was instructed to use Link's Multi Fuel map as a model for my injector settings. Can anyone suggest any remedies for my issue? The car does cough and backfire but definitely does not fully fire and run. thanks! Daniel_ev14_1000_1zz.pclr

That's really unfortunate... I will keep that in mind going forward. I was able to fix it with the correct connector and going over the wiring myself.

Turns out I was sent the wrong harness! It seems that I have an early model board with that 4 pin connector you mentioned. However, I was sent a harness for the newer generation of the board with the 8 pin molex as the expandable ignition out put!

Adam, they are not connected to the ignition expansion. The provider of the wiring harness has them connect to the other expansion on the board. Does link provide a connector and pin kit for the ignition expansion plug? I'd be love to correct the wiring if that's the case.

Hi all. I recently got the g4+ pnp for the st185. I synced timing and got the car running with the stock distributor as well as 540cc injectors. I've since made the switch from stock ignition to a 1zz smart coil setup as well as bosch ev14 1000cc injectors provided by Link. I'm having some issues getting the car to start now. I've set the deatime values for the injectors as well as dwell for the coils and I believe they are wired correctly. The provider of the kit instructed me to turn off Ignition Drive 2-4 and turn on 5-8, which I did. I was also told to depin Aux 6 ( pin 52 ), which I also did. I had an issue with coil 1 getting extremely hot which led me to believe that they coils are either assigned incorrectly or the wiring is incorrect. This setup uses the cam trigger. Wiring goes to the expansion slot on the ecu board. I believe it gets power from the OEM ignition coil connector. Would anyone have some insight on this? Maybe I have settings configured wrong? Thanks! mr2_COP_1000cc.pclr You'll notice that I changed the fuel model back to traditional for troubleshooting purposes.
