detonation????
 

I have the hack done and the car feels good but it detonates everynow and then in first or second but it never does it in third and i get a check engine light on when i boost everynow and then. this is all on a d16a6 what the hell is going on. i have colder plugs and the fuel is set on -35 all the way across on high. the car kicked the ---- out of my brothers rsx type s the other night but today i couldn't even beat him by a nose. boost still reads eight pounds could it possibly leak and still read eight pounds? can old spark plug wires cause any of the detonation?

Tell us exactly what you have for a setup, all the settings on the AFC, and what your ignition is retarded to. Sounds to me that -35% is awfully rich especially if your using 450's.

i have a d16a6 with the following

walboro 255 fuel pump
450cc blue tops
safc II now at (-31 all the way across)
td04 (8psi)
side mount intercooler
MSD 6al
MSD BTM retarded 1 degree
1G blow off
NGK 7 gapped at .028

runs good but sometimes it pops and makes the check engine light come on and it won't boost until I turn the car off and on again. what do you guys think.

Re:detonation????
 

-31%?You should be at like -38% or so.If you were at 35 before and you went up to 31,your adding fuel.The lower the #,the leaner the mix is.Like I said befor you have to be at like 38% or so and go frome there.

Re:detonation????
 

NO.keep in mind you are going - not +.So if you go 38 that is less fuel than 31.0 will be 450cc.at 31% you are at 419cc.At 38% you are at412cc.The higher you go in the negative the leaner you will be.Its basic math!

Re:detonation????
 

so what should i do go up higher and that will fix it. I figure the at 31 i'm super rich so that makes the car run safley right??? I know how to do math if my car is detonating i need to add fuel not take it out.

Re:detonation????
 

It can also detonate frome being too rich.
