XFI and 50lb High Z Are you saying that the cranking fuel table factors and the after start fuel table factors are applied on top of the warm-up enrichment table (vs. coolant), so that by raising the warm-up enrichment table (vs. coolant), I can lower either or both of the cranking fuel table...

I'm using an XFI and 50lb high Z injectors. For cold starts, I have to crank up the after start fuel curve off the top of the chart to keep it running after it fires, or it stalls out. The car runs fine, there does not appear to be any vacume leaks and the O2 readings are reasonable. Is anyone...

I actually have a problem with my Volvo, a spark plug electrode broke off and fell into the cylinder. I want to see if it's still in there and did it do much damage. The spark plug hole is vertical and I dropped a minature light down into the cylinder, but because the hole is recessed about 5...

Anyone have a recomendation on a decent borescope? I can't go for the $3,000 variety, but I've seen several for around $500. I read that some are dark and don't work very well. If anyone has ever used one that worked reasonably, let me know.

Tom, PM sent.

I'm interested Tom, I'm interested, but do you know where I can see the compressor map for the TE69. I tried to find it on the web, but couldn't. I want to see if it is what I'm looking for.

Does anyone have or know a link where I can get the compressor maps for the Precision PT66, PT67 and PT70 turbos ?

Phil, I saw an old posting from you looking to sell a CPT66, but there we no replies. Did you ever sell it, or is it still available ?

Has anyone modified the stock exhaust manifold by welding in a flange for an external wastgate like a deltagate or racegate? Does anyone sell a replacement for the stock exhaust manifold that has an external wastgate flange already in?

Does anyone make a car cover that looks like a grand national? I've seen NASCAR car covers that are used when it's raining, and they look like the car, sponsor logo's and all.

Air Temp The air temperature is one factor in calculating air density for fueling.

Air Temp Sensor for XFI I put mine in the upper plenum on the passenger side about 1/3 of the way down from the top and 1/3 of the way back, from the front. I had to extend the sensor wires to reach. Jack Cottom told me I could use the stock air temp sensor. Put some anit-seize on the threads.

Is anyone running a stock turbo with a good front mount intercooler, like a PT&E. What air temperatures are you reading in the upper plenum at 15 - 20 lbs of boost? I'm using a stock air temperature sensor in the upper plenum to feed an XFI, and the temperatures I'm seeing are under 100 degrees...

Fuel Pressure Thanks guys. I have to check the filter. I have a Walbro fuel pump, with a hotwire kit and new line from the filter to the rail.

I want to make sure I understand how the adjustable fuel pressure regulator works before I swap out what may be a malfunctioning part. Am I correct in assuming that the fuel pressure regulator should increase the fuel pressure by the boost pressure? I have 42 psi of fuel pressure at idle with...

2 Step Activation O.K., since I am using a stock DIS, can someone give me an example of correct power adder tables for 1st stage activation, Power adder hold or clutch activation. Is either one better/easier than the others? Also, PA hold and Clutch activation have a signal that arms it. How is...

Logger Works, 2 Step Doesn't The loose contact appears to have been the problem with the arming of the logger. So by applying battery voltage to B19, this arms the logger. I still cannot get the 2 step to work. Maybe I don't understand section 24.6.2, and it's "NOTE". I thought it said that B19...

False Alarm - Maybe It appears the contact that I inserted into B19 may not have seated in the connector completely. I just noticed that when I mated the connector and the XFI, the contact pushed out the back of the connector. This might explain the problem. I'll update with more data later.
