Racking my brain on this one guys. 7mgte, maf 1st gen, 57trim, 550s. Car started smoking at strange times suddenly. Shortly after that it started "chuging" at idle or camming. Would randomly loose tps response but through all this no flipping codes! Replaced the GM maf then suddenly starts boost...

What are you going to run for your ignition? The igniter is the weak point of this whole thing but these coils give you so much room to grow. Aem is even compatible with this. What you need is a stronger controller for your ignition. I would keep the setup though your not going to find anything...

Ive been running this setup since oct. Occasional 14psi and the timing light will run off the two wires going to #1

Harness is 60 shipped. You will have to contact Nathaninwa for plate availability.

Two things. 1- check and make sure the main harness going to the coil harness is in good shape. If the wires are pulled away then it is arcing and firing the other cylinders. 2- check your plugs. Im currently running mk4-t denso tt #4504 i think. Both of these happened to me and both were the...

I will pm you info. Also im running fleabay coils with no problem. Running for several months now at 11psi. true you get what you pay for and the accel coils or dragons would be ideal but this was built to be a cheap upgrade beyond the IS coils. Not to mention its sexy... invest in strong coils...

Power to the coils is supplied by the 12v feed for the ignitor straight from the ecu.

Yeah man. Still making harness. Factory plug?

Sorry let me clarify. 12 to 14 are my AFRs my boost is set at 11psi . I cant go any higher than that even with 550s.

Yeah i have it stable at around 12 with the occasional spike to 14 under quick spool but settles back to 13.

Guys i just got a question on fuel or boost cut. Im running 550cc injectors and the first gen maft with the 3in. 57 trim ct, walbro 255 ect. Im running 11psi right now because if i turn it up at all it just blows fuel cut. I was under the impression that running with the 550s would raise the...

Hey guys. Sorry for the delay i just got done swaping out my auto for an r154. So i got to run the car and now i can answer some questions. Those having issues with the coil hitting the valve cover. You have two things you can do. Slot the rear hole so the plate will move the 16th of an inch or...

Thanks guys. I had my epiphany last night at likr 2 in the morning. It was a ground. Dirgle, thank you the printouts helped tremendously.

Guys im at my wits end with this. Started the r154 swap in my auto 4 days ago everything is in and bolted up but it wont run! Motor turns over but i have no power at the ignitor or at the injectors. But i have power at the efi relay. Im confused and agrivated if there is something im overlooking...

With both the proto and the new unit i have not had an issue with the clearance. You must have the coil boots to tall. I havent confirmed yet as my transmission is currently trash but there may be a problem with #4 coil. But from my mock up head it looks like the valve cover can be clearanced. I...

What it reads is the kv spike during the ground colapse. The signal wire is more than enough for this.

So the connectors came it today. And none of them work. Good news is i have two connector sets that look almost factory but are not. Good news is they take MT pins which are the factory pins so if you want to replace both sides of the connector then these will work. But i still have not solved...

Nathan you are the man.

I have ordered a number of pins and connectors. I will let everyone know how they work.

That one is slightly different. It has only two tabs in the center as opposed to one keyed tab the length of the connector. I dont know if it will work with the male the same.
