Just finished modifying the intake cover for MAP/IAT relocation (I'm running a CR head). Anyone see any issues with what I've done? Those two are about the only 2 locations that don't interfere with the grid heater, or injector lines/clamps. IAT will be on the left, MAP on the right. Also wondering if anyone knows specifically what material this plate is? I know its cast aluminum, but there's something more to it. I lit up and the gas coming off of it was so bad I had to switch from my normal respirator to a NIOSH filter.
Make sure to keep the IAT to the rear of the manifold. I know that people that relocated to the intake horn created issues with timing and grid heaters.

Good info. Would the IAT location only be an issue at start? As far as I know the grid heater only runs before startup, right?
As for the brake cleaner, I'm aware of the gas issue, which is why I have both chlorinated and non-chlorinated cleaner on hand. I used non-chlorinated.
Optimal IAT is 100-140*F that is near the coolant passage near the rear of the head this why I made that comment. Warmer temperatures give milder (retarded timing). Now below +80*F is what @me78569 is talking about that goes wacky. The timing might jump up another 4* which typically kills the MPG's. Again this is why the IAT needs to stay near the rear of the manifold by that coolant passage. Being both @me78569 and myself can watch timing in real time and the effects of IAT temperature on said timing.
Yes just remember your ECU was tuned in a manner to use iat in the position it is. The edge adds timing on top of OEM, if IAT is significantly cooler after you move the sensor then you may run into stupidly advanced timing.
Personally I would not move the sensor unless you can control timing. OEM Timing does some pretty strange stuff.
My Edge comp has a harness that plugs into the IAT sensor and also plugs into the old IAT plug. I would assume it's either doing a complete IAT fool to get power at certain ranges, or in the least modifying the actual IAT value to add timing.
Oops. My mistake. Well I guess we'll see what happens. I was half tempted to drill and tap a hole in the casting somewhere, just couldn't being myself to drill a perfectly good head that is a lot harder to replace than a intake plate.
Either way, we'll see what happens. I'll watch the temps, if it gets weird I'll figure out a new mounting location
So weird question. How does the winter affect power? Right now my truck runs at 40 - 90 almost all winter long (it's -15C here for usually 3 months straight). How would the IAT affect my power then?
Here's me flipping on the IAT fooler to take IAT from sub 90* to 143 * f you can see timing spike
hard to know on performance side of things but MPG falls off significantly due to over advanced timing. I would imagine your power falls off to, how much who knows. My truck like timing in the this setting, which cold IAT would not allow on a truck that doesn't control timing.
If you look at the data log above you can see how much timing is spiked when IAT is cold. Early trucks seem to use it more than late trucks.
I dont know that you will have problems with the setup, just keep on eye on IAT. if you notice it is too much cooler I would try to come up with a solution.
We'll see what happens. The goal is to get a reliable 500hp out of it on a dyno, which might be somewhat difficult as the last dyno here closed a few days ago. If the Edge does it, great. If not I'll go this route. Either way I really like the tuning capability, but might have a bit of trouble keeping OUT of trouble
Then I'm on the flip side working with IAT to gain the MPG's so warm the IATs the better the MPG's get. Also using Quadzilla Adrenalin V2 logging and also OBDLink LX logging for my MPG numbers. I can tell you that colder the IAT gets the more that line goes downhill not uphill.
I'm still playing with stuff I bounce around quite a bit. Like I data log my IAT and ECT this last trip from Boise, ID to Midvale, ID. Weather was clear about 40*F, running winter fronts yet. As you'll see I'm barely hitting my 100-140*F mark. This is unfooled. Sharp spiking is my exhaust brake blowing hot gases back in the manifold which is normal.
I know the discussion has moved on but I noticed no ill effects where I had my sensors mounted. I had the map sensor a but further forward but the iat was towards the rear. iirc
I don't think it ever would. We need them here for winter starting. E. G I've been driving for an hour now and my IAT is pegged at 13C. Not sure what that does for timing but the truck is running noticeably rougher
What was your outside temperature? I'm guessing about -9*C (+15*F). So this engages the extra timing of the ECM and adding excessive timing due to excessive cold IAT temperatures.
That's the part I love. I only have to fire up my phone "IF" I want to. Like @me78569 said if I want to data log or load a tune yes you'll need it. I've already got ISSPro EV2 Gauges in the truck now. Beyond that, no all tunes and setting function without your device connected. This I like because it gives the illusion of being just a stock truck sleep style. Sure a surprise to the passenger when it comes alive. I could remove both my tablet and cell phone then truck would be very plain jane inside. :smile2:
Yeah that's the plan. I'm just searching for an android device that does what I want it to and doesn't cost a fortune
I'm recognizing your name from all the info I'm seeing on V2 programming. Maybe you can answer a question for me.
On Quadzilla's order page I don't see anything referring to V2 tune loading. Is it something that's in Beta only right now, or am I just missing something?
