Simply adjust at the regulator itself, thats why its called an 'adjustable' fuel pressure regulator.
Don't recommend using one, search the forum for engine fires.

Less power vs chip designed for higher octane fuel.

 

Just bought a set . Can't wait to give it a try ...

 

Just wanted to share with everyone the unboxing as is the culture in the new millennium when new technology is received:



Obviously all still in the boxes and bags - no installation as of yet, but they are going into a very cheap 85 that I found which did not run because of a massive vac leak on the intake.

So I I have done some work to renew the top end inexpensively:






No - the "artwork" in the lettering on the cam covers is not pretty at all. I am not an artist or even very good with paint. Hard parts, yes - but not paint.

Should be running this weekend. Really excited to try these chips with ethanol and see where I get.

 

Brendan, where did you get the new style bolts and washers on the cam covers for your '85?

 

I thought that would come up.
This 85 came with them. And I have an 86.5 that has the old style. I don't think those rules are hard-fast ones. This is an early 85 as well.

I suppose its possible someone went in there before me, but the car only has 130k and it doesn't seem like it.

 

BC, Get the ole girl running well first and see/feel how she runs stock... Once you've gotten all the bugs out, vac leaks sealed up, etc... THEN install Ken's Miracle Chips with TQ Rings. You'll be smiling from ear to ear for a month!

 

Too many changes. Going through hell - keep on going. Should be tight as a drum on vac. Blocking off most stock vac ports except for brake and one TB and of course crank case vent.

I hope to smile anyway.

 

What's the engine#? Maybe replaced?

Only late '86.5 have the new style bolts.

 

I think I wrote it down somewhere. I'll check. It does not have a machined pad for the number. The pad has a cast end to it, and the numbers are stamped in that. Which means the engine may have even less than 130k

 

How long does it take to recive those chips in mail ? It's been a Whole day already , I'm just kidding but they aren't on back order or anything right ?

 

Normally only a few days. Right now, I am waiting on more rings from my machinist guy. Should be done tomorrow.

 

I received mine in 3 days!

Okay....gotta go drive it again...bye!

 

Lucky , I'm stock in Sarasota till 10pm and then 21 hour drive to Chicago to my baby 928.

 

I just put the new chip in and adjusted the pressure as when I start the car the idle is high around 1700rpm , what do I need to do ?

 

If the coolant temp is <40F, the idle may be as high as 1200, or higher, for a few seconds, until it warms up even a little. (This is by design, to more quickly warm up the engine, and help clear condensed fuel in the intake.)

Let it warm up, then adjust the idle to 680 rpm. Insert a wire between B and C on the engine diagnostic plug to stop automatic idle control, use a 7mm socket to adjust the speed at the front of the throttle body. If you find that the idle stumbles when you come to a stop light, turn the idle screw CCW, 1/2 turn at a time, until it recovers nicely.



Note that the best way I've found to adjust the fuel pressure with an AFPR is to set it to 58 psi when the engine is dead cold, not running, with the fuel pump relay jumpered. Setting the pressure while running leads to unpredictable results.
