Re: Coil On Plug Conversion for Stock ECU

new_motor_29MAR22_cop.jpg The NTR bracket is well built, but didn't know about other options at the time. There was some flexibility in terms of using different coil pack spacers. The better option seems to be PrecisionSpeedllc.bigcartel.com . I have a billet cover on order as it is a single piece ...

Re: Coil On Plug Conversion for Stock ECU

@ tuzzio. Thanks, I was on the fence about the $129 Nice Time racing aluminum cover to replace the plastic rapid prototype style plastic part I had. I haven't been on the forum in a long time and I remember seeing that Nice Time (via instagram) had partnered with Wiring Specialties for the Honda K c...

Re: Coil On Plug Conversion for Stock ECU

Not sure if this helps, but I was thinking about a couple of documents on JWT site about how the power transistor signal works: http://jimwolftechnology.com/wolfpdf/MSD%20TO%20SR%20240SX.PDF http://jimwolftechnology.com/wolfpdf/DISTRIBUTOR%20SR%20KA%20CHANGE%20CAR%20TO%20EXT%20COIL%20AND%20TRANSISTE...

Re: Coil On Plug Conversion for Stock ECU

Been a while. I have a rebuilt engine in and bolted up to my bell housing w/ a new 'white bunny' clutch upgrade. I think there is typically a loop on #1 if you buy a harness from wiring specialties like I did for S15 smart coils (using maxima). I'm actually running an SR20DET ECU now w/ daughter boa...

Re: Coil On Plug Conversion for Stock ECU

Running a KA24DET with Maxima coils. Ended up getting a NiceTime Racing S14 timing cover bracket, designed for Honda K series coils, but fits the Maxima smart coils. This was not cheap. I have been offline for a while, the rings on #4 cylinder went out and now have a rebuilt engine. System provided ...

Re: Coil On Plug Conversion for Stock ECU

Yes, Wiring Specialties makes a very good product. Highly recommend them for harnesses & connectors on Nissan's. I found another source for dust covers on ebay for slightly less than Xcessive with free shipping from the Midwest. These seem to be rapid prototpye style material, with a fairly high...

Re: Coil On Plug Conversion for Stock ECU

I went ahead and ordered a brand new set of NGK BKR7E-11's, with factory gap of 1.1 mm (0.043"). The car does seem to purr at idle like a modern engine with COP, I think my old S14 dizzy coil was weak to begin with from age & all of the heat soak from the Turbo kit. Before I went with the X...

Re: Coil On Plug Conversion for Stock ECU

I've been able to get my S14 running in my Garage, but I live in Wisconsin and don't drive mine in the snow. I noticed a few minor issues with the wiring pinouts on the ECU, nothing major. I have an S14 w/ S13 Enthalpy ECU & adapter harness, I've tapped into per the above instructions. I think t...

Re: Coil On Plug Conversion for Stock ECU

Up and running with "Dog.Tuning" Nissan COP converter box on my S14 KA24DET. Using NGK '01 Maxima Coils and Wiring Specialties S15 'smart' coil sub-harness and 2 x 3 mating connector. Used an Xcessive Engineering internal coil delete (not needed). It may be possible to use the internal coi...

Re: Megasquirt MS3X KA24DE wont start

I assume you removed the DIY Quadspark, when you went with '01 Maxima "smart" coils?

Looking to go COP on an S14 KA24DE as well.

Re: Coil On Plug Conversion for Stock ECU

That's good to know. I've already ordered a S15 'smart' COP sub-harness from Wiring Specialties. Can you verify the dwell & duration are correct? I researched a Haltech stand alone and they seemed to have a chart of for rpm vs. voltage for S14/S15 SR20DET coil controls. The $1500 Haltech is out ...

Re: Coil On Plug Conversion for Stock ECU

3 years later... I would be interested in one of these "Nissan" COP Converters. After turbo rebuild, needed to reduce gap to avoid spark blow-out on a S14 Enthalpy tuned ka-t with Z32 MAF, DW 550cc injectors to about 0.028 on NKG BKR7E's. Still get some issues with a heat soaked engine aft...
