Boom bitch!!!!

Tune it? I figure changing the plugs, backing down timing and having a 255lph should be enough to compensate.

Did you also switch to a colder plug range?

Yes. Autolite 24

maybe the fuel solenoid stayed closed! seen it happen

Only 1 plug failed, so I don't think so.

Went lean some how.

[91CoupeMike]

Probably shitty intake design

Now that I saw a better pic...that isn't from incorrect gapping... lol. There isn't enough current in the plugs to do that, even if it was grounded out.

I'm thinking either bad distribution of the fuel or, that aftermarket bullshit maf is fucking up your fuel trims.

I have a stock maf

Couple of things. First your car shouldn't run 13 anything AFR all the time. This means either the wb is not calibrated correctly and reading almost a fill point too rich or your oxygen sensor isn't working.

Second, try a 3923. Your plugs are too hot. Was that #7 that burned? I always ran non projected tip NGK 8 plugs. Never had an issue like that. If your wb is wrong then it was too lean. Did you ever cut off the threads and read the plugs after a wot pass? If you want it right you have to. New plugs must be used each time. At least on the holes you are checking. I always used #7 because it was my problem child.

Was that the first pass on a full bottle?

[91CoupeMike]

This was number 8, and I pulled #1 the first time I used nitrous and haven't checked them sense.

It reads 13.6-13.9 all the time, I fresh air calibrated it when I installed it. I thought it was odd for it to be running rich, but on wot it shows 12.5-12.8, which matches what it showed on the dyno.

"never detonated"

lolz

It should fluctuate rapidly between 14.2 and 15.1. Close loop targets 14.67 and it dances around that. Either the wb is incorrect or the oxygen sensor isn't functioning properly. You really don't need a wb to tune for nitrous.

Use a full bottle, install a fresh plug in #8, I did this in the parking lot, running it all the way through 3rd, turn off the car, coast into parking lot down the road, pull and replace #8, take home and cut off threads. Post pic of plug.

Set base timing at 6 until you get this straight.

[91CoupeMike]

Hmm, I wonder why the wideband is reading wrong. That's really odd. I was under the impression that 14:1 was target AFR with narrowband set ups.

[MstangsBware]

Willing to bet piston has a matching matk on it. Denotation is a bitch..

[91CoupeMike]

I didn't hear anything, lol

[racrguy]

Dumbass.

How's that modding/racing your daily workin' out for ya?
