i just purchased some autothority chips but i dont know if they are stage 1 or 2... and i dont know how much boost they support. anybody know?

this is what the chips say on top

CARB EO# D-228-1
POR.01.951.220 KLR

CARB EO# D-228-1
POR.01.951.220 DME

thanks

I had some autothority stage 2 that had these same numbers. NOT positive this is confirmation though. They could easily have the same numbers considering the application is the same. I really had good results with the chips but beware buying 2nd hand chips, it is a risky business.

I can't confirm, but I don't think you have Stage II chips. Here are pictures of mine when I changed chips:




As for boost, I think they supported ~14psi, but I cannot confirm that either.

so does anybody know what boost stage 1 and 2 supported? that would help greatly

stage II is designed for .95 bar but it is up to the end user to determine the hole size in the banjo bolt in order to achieve a maximum of .95

dhall615

so 13-14 psi?

The autothority stage 1 was just a DME chip for stock boost. The stage two was the DME & KLR chip with the banjo bolt for raised boost. The stage 3 was the MAF kit. According to APE in the mid 90's at least.

ah so i "should" be safe to turn boost up to 13-14psi but no more? they are authentic ships...

Darwantae951

How are you controlling boost?

If anyone tells you that you "should" be able to turn up the boost any amount, you should smack the crap out of them. Unknown chips + more boost - wide band device, to measure AFR = BOOM!

At least get a narrowband to use as an dummy light, a wideband is better if you have the money. Do not go over 15psi.

check to see if you have the correct banjo bolt

i am going to use a mbc to control the boost (black *** from LR). the chips are autothority and from what i have heard since i have 2 chips that means that it is stage 2... so that is how i was going to judge how much boost.

dhall615

i was also told that if i had a mbc i wouldnt need the banjo bolt...

944CS

wrong, Autothority stage two chips are designed for use with stock cycling valve and a jetted banjo bolt. Don't waste your money on a Lindsey MBC
