Vargas B58 Coil Conversion

Sounds like people are getting really mixed results with us. I don’t know why. anyone Have an idea we can’t all be idiots

Edit: I thought your email to vtt looked completely reasonable

Haha thank you I didn’t think it was unreasonable. Aside from the request that “I need it tonight” which I realized probably wasn’t gonna happen.

I don't know if this is the only issue, but there seems to be some variation between some types of b58 coils where the springs supplied with the kits make contact with some types but not all (I posted pics from a thread about this a few posts back). I don't know if it's clear if this was a design change to the b58 coil, or variation between manufacturers. If you have the coils that don't make contact, the car can still run because the voltage is high enough to jump the gap and get to the spark plug, but the motor may not run right because the energy gets used up jumping two gaps vs. just having to jump the spark plug gap. That and you get the coils burning up from that spark jumping where it shouldn't need to. I know Nexsys was offering to send different springs to customers who had this problem, but this was probably a year or two ago. I assumed people making b58 coil conversions would eventually work all these bugs out, but don't know if that's happened yet.

Nexsys seems helpful.

Will definitely buy the nexys kit if you have success with them thx for sharing

Yeah he didn’t start his car…

I know lol. Just looking at possibilities. I want them to work just as much as you. I was going to get a hold of those boots and do my install. I don't plan to remove my spark plugs. Wish me luck.

The b58 plugs are taller btw if that makes you more comfortable

VTT is shit.

Yeah I tried it w both b58 and s55 sparks same result

The dwell time adjustment is pretty small from the S55 stock map compared to the B58.

I have been running B58 coils for well over 2 years, it sounds like you dont have the longer spark plug boots, because my car ran noticeably smoother with the B58 coils, even at idle.

Are you able to run a wider gap after the B58 kit?
Also I'm still thinking if I should select the drop-down menu or not.
Thanks

No you still should, get the kinks worked out for me

No, I run stock gap of 0.022" but I dont get any spark blowout and it also helped clean up some timing corrections.

Wouldn't it open up the potential for a larger gap? Or is it not THAT much more powerful.

Most people at 700whp like Chet run about 19-20 thou.
I'd say 22 is a good level that still idles, starts and has good drivability.

Most modern spark plugs create a strong spark, even more so with the B58 coils. There is a point of diminishing returns with expanding the plug gap.

I have a funny data, with BM3 “Nexsys” selected. Timing is horrible, higher gear high rpm misfire CEL. I tried different gap and switching around coils with no difference after testing. I’d say it got me 20 times CEL on the road. When “OEM” selected, timing is perfect in all kinds of ways, no misfire with plugs/gap/coils untouched.

Sounds like something is off in their calibration because there is only 1 map that needs adjustment and it's not complicated

What plugs and gap are you running?
Do you notice any benefits?

[ericlr1225]

0.022'' flexfuel. Idling is perfect. I didn't notice any difference, maybe it's a good thing? lol
