Whoops - Low-Z Injector grounded
Well, I messed up. I'm installing my MS3, and I'm using JBPerfs 2.0a peak and hold board for 750cc low impedance injectors. I got impatient and soldered in the tip122's before drilling the heatsink holds in the case, then had to reflow the solder to get the holes to line up. I got impatient/frustrated with aligning the screws and making sure they didn't ground out in the case, which resulted in..
https://lh4.googleusercontent.com/-u...0/IMG_4529.JPG (Please don't judge the whole of my soldering by these few joints) Didn't notice until I smelt it / saw a little bit of smoke from the fuel rail. What do you think the chances are that I ruined the injector (hot to the touch, smoking slightly), and the rest are OK? I've replaced this tip122 already and will bench test before I hook it back up, and removed the injector to send it to Deatschworks for cleaning/testing.. |
I wouldn't trust it. Fuel injectors are critical - if one fails you're liable to lose an engine.

Looks like all you did waas ground the output. Clean the solder and move along. |

If nothing else, it's entirely possible that while the injector hasn't completely failed, you may have damaged the insulation on the winding, possibly causing a few minor internal shorts and changing its characteristics relative to the other 3, and quite probably setting it up for an early failure. |

Yeah. I didn't read tthe part about a smokin warmed injector |
too many TLA's there I don't know - DW, FIC, ID ?
Might as well pull all 4 injectors for a cleaning and flow test.. |
deautchworks
fuel injector clinic injector dynamics |
Has DW gotten a bad reputation since the last time I was active on this board (~ 2 years ago)?
Guess I'll start looking up threads.. |
