Lean burn Honda Civic sedan: 93 Civic d15z1 swap into LX 4 door (VLX)

Thanks!!
I did feel the rubber intake tube and it certainly wasn't as warm as the metal tube. They are different materials so it's hard to say. When I get to work tomorrow I'm going to use my infrared thermometer and test some spots with it. A good test would be to cold start it and get iat readings after a minute. Then drive it to operating temp and check it again. Then unhook the warm air and do the same tests and compare.

On a side note my gauge pod shipped and should be here tomorrow or friday

Is your MAF/MAP sensor before or after your mod? If your warm intake is bypassing that sensor, you could be under-registering the air flow. This could cause a lean condition but not in the way you intended.

The warm air is sucked in before the filter. The map sensor is mounted on the throttle body and the iat is on the intake manifold. The only downside that could come from this mod is if the air gets too warm. I've read around 100 degrees is optimal but if it's higher it might work against you

This morning I got to work and shut the car off. I Immediately got the infrared thermometer. Right by the clamp measured 100 degrees. By the airbox measured 80. The plastic tube right in front of the throttle body measured 70. The metal pipe cooled dramatically within seconds. I'm thinking some insulation might help on the metal pipe to keep the temperature moderated. I really need to hook up a voltmeter while driving to determine what it needs. It might be fine the way it is but until I test the iat voltage I'm guessing

From what I recall when I was setting up my WAI, lots of modders on here seem to like 120s, 130s, and even 140s. I try for 120s and 130s max in summer (over 100 minimum in California's "winter"). I seem to recall suggestions that going over 140s is risky.

Thanks!! I have a voltmeter hooked up to the iat sensor. I'm measuring the resistance value and I'm going to record the figures at 3 different situations when I go home. It's harder to monitor than an obd2 because I can't use a scan gauge or scan tool

well i was unable to register readings for the iat while i was driving. there are other ways to check intake air temperature but its way too involved. i did notice its alot easier to go into lean burn with it. i might add insulation to it in the near future but for now the next modification is the gauge.

The wide band controller is mounted. I ran the wiring through the firewall right by the harness I made for the engine conversion. The gauge pod is the one from eBay a guy makes. It was mostly finished I just had to do some light finish sanding. It goes in the center of the dash and replaced the vent. I blocked off the louver so air won't come through. I need to pick up some paint for it yet and do the wiring.

Thanks!!
But of course. It will be tan to match the rest of the dash. Only trouble is finding the time to take my tired behind to Walmart to buy some plastic paint :/ Walmart drains my energy every time I go there. It's like a sucubus
