What wires are those?

Lmk where you can get all the parts for 5 bucks cause it would increase my profit. When all is said and done with PayPal fees shipping costs materials I make 25 bucks.

Lightning PM me what's going on in detail

Sorry, I meant wire but nonetheless the GREEN wire. Given, I haven't used a "SendItRacing" ICM bypass box before, but judging by your diagram the tachometer output from the Crane Box isn't needed unless you didn't draw the wire connection to the OEM harness or am I missing something? I also am missing the ICM bypass box wiring schematics/instructions as well so maybe that is where the answer lies.

The icm delete is four wire. Power ground a21 at ecu and output to the ignition box.

Its obviously wired ok if the car runs fine until it gets hot. Issue with box or coil here.

If it is so obvious then why are you having problems and asking questions? If something was wired incorrectly things could heat up/fail instantly or over time. If you suspect the coil or box then maybe you should be using something a little more advanced than your hand. They do make tools for this type of stuff. Good luck fixing your "mysterious" issue.

Starting to think it was a bad ground. The washer is rubber on the bottom and the ring terminal was never touching the screw on painted metal...doh

Chill lol

I was very careful and took alot of time making the harness, so I was confident it wasnt something just shorting out.

So back to why I was suspecting wiring... I wasn't sure what other wires were needed and didn't want to default to a bad ground. Sometimes it is easier to just answer the questions asked and help will follow. If I ask a question there is a damn good reason behind it - I was just trying to help so maybe you should chill... At least you figured it out hopefully.

Still having issues with ignition, I'm at a loss almost.

  • Replaced the coil wire with new one pre-made MSD, same issue
  • I hooked up my stock ignition back up with accel coil and it feels much better everywhere part throttle but still cant make it past 26 lbs or so.
  • Replaced cap and rotor with new OEM Honda, and fresh plugs gapped to 0.017 and same issue.


Last thing I can try is plug wires. Sending the coil and box to crane to look at to rule that out.

Another guy contacted me with issues i think he was running the crane box. I don't see why it would be an issue though unless the box is no good. Initially when i did my igniton system the first summit box i received was no good it kept breaking up. Got a replacement right away from summit and now I've been on that same box and coil since.

What wires are you running ?

eCtune

OEM NGK's. I may order a new set, this one is a few years old. Its crazy, but I've seen cars go from not running at all to running amazing from a simple wire swap.

You could always ohm them out first to see where they are at. I personally HATE swapping parts without finding the problem first.

Well I think I may have stumbled on the problem.

The only thing that is different currently between last year and now, is the dust shield inside the distributor is out because the Accel coil just fits better without it. Apparently this keeps the cap from arcing to the distributor body under high load. There was a warning about it on the crane manual, doh.

Would make sense that it was worse with the crane ignition because it has more power and the energy is coming from the cap and not the internal coil.

I will test this theory this week

Maybe the icm output from the ecu? Loose wires or corroded wires?

Have you went through your harness and opened up the ecu to check for damage or just swap out distributors and ended there?

It would really suck to drop 400 on a new ignition setup to just run into the same problem.

Have you tried to borrow an ecu to see if the problem carries over? What plugs are you using? Is the motor grounded really good to the frame? Battery also?
Ill update this for him.

He found a loose wire to the icm last week :cough: :cough:

I think at the ecu connector.

It happens more times than parts failing. Not just on cars but all electronics.

You got your ban lifted? Or it was a temp?

Im not looking to get into a drama war.. but nobody likes scammers. The ban was lifted for various reasons, none of which are my business. Nikos,rocket and vtecmasta wont get their bans lifted..i do know that though. Wantboost and Muckman were probably two of the higher ups that really wanted to get the ban lifted, there were more, but I know that these two really stepped up to get me back on here sharing knowledge.

Back on topic, I've seen a fair share of connectors at the ECU come loose more often, then the actual plugs at the dizzy. Hopefully this gets resolved.

Yea I've actually seen the connectors from the pins to the PCB in the ecu come loose more than once. it's mainly from vibrations and the ecu getting bounced around. most people I see with chipped ecus simply lay them in the floorboards and don't actually mount them to anything

Yeaah well im the savior here so na nana na na .

I just wanted to update this because people think a component is always the fault when most of the time its not.

People need to take the time to learn how to use a multimeter and read a schematic.
