I"ve never been able to figure out a knock issue I have in my stock 86. Recently smogged, car is bone stock including chip currently. Boost currently at 12-13#. On WOT runs from 0 or a slow roll I get blips on the Casper's knock gauge and KR readings (usually 2 or less) on the SM at WOT...

My car had started running rough and throws a code 32. I checked the EGR and find that the valve is pulled open at idle. My understanding is that it's supposed to be closed at idle and the solenoid allows vacuum to pull it open when appropriate. Disconnecting the vacuum line to the valve, the...

Wondering if anyone can help me figure out why I get KR (up to about 4 degrees) on only about 10# boost. Basically a stock setup. This KR problem has plagued me from day 1. With boost limited to 10#, it's an intermittent problem. Going WOT from freeway speed I get blips on the knock guage at...

I'm chasing vacuum leaks on my 86 and noticed that the EGR solenoid doesn't hold vacuum. Hooking the Mityvac up the the larger of the two hoses coming from the EGR solenoid, it doesn't hold vacuum at all (car off). I decided I might have a bad EGR solenoid so I decided to "T" a vacumm gauge...

In my search for a lowish boost Kr problem, I decided to make sure I have no big vacuum leaks. I 've been replacing all the vacuum hoses and using a Mityvac to test for leaks. I was surprised that hooking the Mityvac to a short piece of hose, then to the vacuum nipple on my Bosch adjustable...

I've only got an Innovate LM-1 with the RPM convertor. I'm already logging RPM, TPS sensor, and boost using a 3 bar map? What else are ya'll logging? Is there a way to log MPH without a PL? Thanks

I got a 3 bar MAP sensor to log boost with my LM1 but am getting odd readings (using rpm convertor, not auxbox) . When setting up the channel that you want to log on, what parameters do you put into to tell the computer how to imterpret the data (ie x volts = y lbs boost). I grabbed some...

I've been trying to figure out a knock problem for a while and have started using DirectScan. 1. Does real knock go away if you keep your foot in it? Reason I ask is that looking through a bunch of files I've made, I always start to get knock (usually starts at a fraction of a degree then...

I'm fighting a knock problem and notice that voltage recorded by SM is around 12.2. I'm afraid low voltage is causing me to lean out. Straight off of the alternator at idle it reads about 13.2 at idle. When the Ramchargers dual fans kick on, the voltage drops to about 12.5 (read with...

My car's been converted to vacuum brakes, but the previous owner gave me the powermaster setup which he said still worked. Is there anyway to bench test the motor, accumulator ball etc so I know if this thing is worth keeping. (Which leads to jump to test motor etc.) Thanks

As it says, anyone have a plug and play adapter to install a T+ so I don't have to hack into my harness? If you don't have one, any idea where one can be purschased?

I'm trying to install an LS1 maf and would like to use a 3.5 in pipe. I'm looking at the Big Mouth Shorty kit, but they recommend using an angle boss for the IAC sensor because of clearance issues. Problem is that boss from BOPengineering costs 60 bucks plus shipping. Seems a bit excessive...

Got a stock 86 and am getting knock at 10-12 lbs boost on 91 octane ("premium" Ha). I'm looking for a chip that will give me the best performance on crappy gas. I've got a T+ and LS1 MAF that I need to install. What do you recommend? I've thought about the Extender and Turbotweak. Any...

Had a little problem with communication (he had left town), but bottom line is that my part was sent quickly, packaged well, works well and price was good. Thanks.

Anyone know how much you torque the three bolts that hold the rocker arm shafts? Thanks

Does anyone make a 3.5 inch MAF pipe (for LS1 MAF) that has the bends in it (as opposed to a straight MAF pipe with bent connectors)? I like the looks of the pipe with the bends better than the staight pipe. Thanks.

Interested in used DS. Must be complete and in very good shape. Thanks.

Bought some used parts. They were packed well, delivered promptly and best of all, for used parts, were in outstanding shape. Great price.

Thought I would leave my own feedback on this and not bandwagon someone else's. This happened a few months ago, before all their bad publicity on this board. I ordered a 3 in ATR DP. Said that they didn't have it in stock, but they would be able to ship it within a week. Cool. They...

I've been getting knock at or under 10lb boost. Put a fuel pressure gauge on and was getting only about 30psi with the stock pump /pressure regulator. I figured the pump was worn out so I replaced with a Walbro 340 (not hotwired yet) and a used adjustable fuel pressure regulator. I still...
