What is the purpose of the AIH Delete. I did a search and found it mentioned a bunch but not a reason. Is it part of another mod or just getting rid of an unnecessary item?

I'm getting ready to order my AE program and Fuel Rail crossover from RiffRaff but figure I'll go ahead and get the plug with Boost sensor outlet since Clay's shipping me stuff anyway.

Thanks, Paul

 

i would say, it opens up the airflow inside the spider assy, also, it gives you a "spare" relay, for if/when your GPR takes a dump.

 

Is the heater not needed?

 

if a manual truck, then trans temp i wouldnt have.

If your not towing much, and you got a auto, then i 'd say, trans temp as well. I would keep the EGT only because, if your even stock running, i've hit 1200+ before on mine, and mines stock. Boost, not having it, will add to your mpg... Maybe boost gauge too, a simple water with soap bottle can detect a boost leak, also, it can probably be visual too.

 

Thanks Timmyboy. As you can see I had a posting glich and you were so fast you answered before I could fix it. I do have an auto tranny, 285000 miles. Was wondering if I needed that one for keeping an eye on the old girl.

 

The purpose of this product is to remove the restrictive Air Intake Heater from the intake air flow. Removing the AIH coil will not affect cold start up in any conditions. The PCM only commands the AIH to activate to reduce white smoke during extended long idle periods at low ambient temperatures. Specific conditions must be present before the heater is activated per Ford:

• Ambient temperature must be below 32°F
• Engine oil temperature (EOT) must be below 131°F
• Vehicle power must remain between 11.5 and 15.0 volts
• Parking brake must be applied
• The transmission must be in Park or Neutral
• Glow plugs must be off

 

That's as good an explanation as I could hope for. Unnecessary equipment.

Thanks

 

It's one of those 1% components! Only 1% of them will ever be used! But we all get to enjoy the 30% restriction in airflow they ^so generously provide! We should all feel privileged to be graced by their presence!

Back the truck up..first off, OP, where you located?

 

Its just one of those fancy emissions things. Makes the truck not smoke when its sitting there in the cold at idle, and like Clay's post shows, its rarely used. IIRC, you should put a resistor in its place though. I wanna say one of the tests you run with AE looks for that and if its not installed, the test won't run.

EDIT: Found it! https://www.ford-trucks.com/forums/1...eting-aih.html It might affect running a buzz test or CCT

 

Only if you remove the relay will it give you an issue with threat test, not with just removing the plug.

 

Im sure Jody could program that out of it in his tunning? maybe have that as an option on his tunes....like a high idle option. IDK...maybe it would have to be done at a live tune session?

 

It's easy to turn on or off a function in tuning a PCM! But the PCM still knows that function exists and activly looks for it across the buss, if it is not there the PCM will throw a code, that is a pretty deeply embedded algorithm, I'm not sure if the ford PCM allows for that rewright of code at the at the tuning level used in our programming? That's a interesting question that could lead to a lot of other really cool functions being added or subtracted fror the PCM!

Sorry to jump in but my question is what all would you need to get rid of to completely delete the AIH?

 

I used this plug:

Riffraff Diesel: RDP AIH Tapped Fitting

and the dfuser code eliminator at the bottom of this page:

DFUSER Diesel Performance Products Exhaust High Performance Part Diesel Intake Diesel Power Chips
