Or does anyone have an Idea on what is causing this? Thanks any help is appricated

You are a real winner Marques. As far as I'm concerned, you and your over populated 1992-1995 Civic EX's can get RICED. How many headers do u have on your car man? Have u checked out those new APC tails YO. How about the Faze audio getup. That ish is off the hook brah.

At least this guy has a turbo kit and puts down almost 270whp on 6psi. How much you lay down. I'd say 103whp. I'd say for a grocery getter, your car must turn heads at Festival Foods. I think it's funny how you take all your anger out on a kid who has a hot car with a turbo kit. You're still mad that daddy made you stick with the EX economy fuel burner. And don't try to sound inferior to this guy like you can install and fix everything and are the diagnostic expert. Put a sock in it, you and your SOHC motor. But take my advice and look into Autozone Performance Products so you can go fast Mang. I bet you will ****** 4th gear with those TypeX floormats and the 2Fast2Furious seatbelt pads.

As far as answers for your question about the Digital 6, I would just double check every connection again and make sure you are tapping into the right wires. I have been told many times that all you ever need for even a 600hp car is a SS Blaster Coil. The 6 and 6AL really aren't anything special. Good Luck. keep us posted with what you find out.

im confused when you mention about the 2step part? ar you using the 2 step or jsut driving? the backfiring might be a missfire caused by plug gap. it prob wasd affected whenyou installed the ignition , might need tighter gap

I'll try that Thanks....and also it was when I was just driving and not using the two-step.

You will be safer running a gap of .030 anyways. The thing that is kinda weird is that usually when you run the MSD Digital 6 or 6AL, you usually don't have to run that tight of a gap, but it doesn't hurt anyways to get it in between .028 and .032. So if a tighter gap works for you, then maybe there is something wrong with the unit you installed or it wasn't installed correctly.

On the other hand, makes you wonder if what you installed is worth the money and if it's even working. The tighter gap may fix your problems, but leave you with another product that isn't doing its job.

I have the gap set at .03.....and everything else has been working great......just that freakin back fire is loud enough to make birds drop straight from the sky......I'll double check my gap though.Thanks

Explain a little more. Do you mean rev-limiter and shift. What rpm's are you shifting at. If its at rev-limit, its because of your rev-limiter, it cuts out two cylinders from spark so
the fuel doesn't burn and gets pushed out on exhaust stroke. Then burns and causes pops and flames. Don't worry about it , my car pops every red line shift and when i use the 2 step. Someone correct me if i am wrong.

I have the two-step set at 4800 and when I shift at 5000 to 5300 is when it does it....it not every time more like 50/50 but it is a death rattle for sure. Mabey I just paranoid because I am running open dp and it way louder then a normal backfire?

Hondatec38

I like that sound. The flames are cool too.

utahbmx

Alright.....so the general opion I am getting is that this is no big deal right? and I should stop being a sissy........I just dont want to f-up my motor since this is my only car. Thanks for everyones help

PM-Performance

check all your rev limiters.no one care s what the 2 step is set to , thats for launching ,t hat has nothing to do with it

utahbmx

but the backfire changes based on where the two-step is set at

PM-Performance

i think you have something confused. the 2step is a rev limiter set for launching. you need to apply power to that wire for that to even be activated. so unless you wired that thing to constant it shouldnt be kicking on unless you switch it on . Now if its the top end revlimiter you are talking about then just set that to where you want the revlimter to be. Simple as that

utahbmx

right....I know that the two-step is hooked up right...I purchased the hondata clutch switch so that it would function properly for launching. but depending on where the two-step is set at is where it will have the backfire somewhere around 5000 rpm from it.

PM-Performance

once again . IT DOES NOT MATTER WHERE THE 2STEP IS SET UNLESS YOU ARE USING THE 2STEP
now question is . . . . . are you using the 2step?
if it is hitting the 2step, then guess what . . . its wired wrong.

utahbmx

yes I have the two step wired up and set at 4800...it is activated by the clutch switch...which means every time I push in the clutch it is activated so if I'm at 5800 and shft it will go into a still mode but if I'm with in 500 rpm of the two-step rev limit it will go crazy and backfire....Thanks for your help

PM-Performance

i dunno dude . i have no idea what your talking about. Set the 2step at like 10k to diable it and see if everything works fine. if it does then you have it wired wrong.
