First thing I'd like to note.. I THOUGHT I had my cable and TPS sorted out but I noticed in the log that that is clearly not the case and I apologize, I am at work and have been tinkering with maps and just wanted some feedback on things I can improve upon, and had a question

Is my IAT normal? I am dumping externally and the dump tube sits less then an inch from my intercooler piping, I am going to heat wrap it my next day off but I still don't like how the temp rises.

Mods are in my profile but for those that don't want to look.. wally 255, afpr, PR FMIC setup, PR 44mm ewg, FP 68hta set to 22psi, stock block, stock head, custom 3" intake pipe, 1g bov recirc, FP manifold, MBC, 3g maf. AEM wideband and autometer boost gauge.

Thank you in advance for you patience, I've been holding off on asking any questions until I got most everything sorted out.

I checked some things, made some adjustments to my fuel table and did another pull.. this is what I ended up with.. I'd just like to know if I'm moving in the right direction.

Looks like it needs more fuel in the 600hz-1300hz range, but the top of the pull seems ok. It's just my opinion but I like to avoid big steps in MAFComp and OpenLoopMaxOct. There's a decent jump between 800hz and 900hz, and there's also a large step down in AFR in the 3000-4000 range. From the log it looks like those are the areas you're going lean. I'd smooth out the MAFComp line a little, and maybe have the 3500 column in OpenLoopMaxOct be a step between 12.5 and 11.3 and make another pull.

Thank you, I'll try to smooth out the transition a little bit, through my reading it was suggested to try leaning out the areas right before boost to help spool. I'll make some tweaks before I leave work and do another pull on my way home, I did a boost leak test last night and tweaked my MBC so the pull tonight will be somewhat different. (Boost leak test comes out fine, no leaks through anything except my PCV valve, but I have the check valve in place and I was still getting air coming through the valve cover.)

That's true you can lean out some to help spool, but I'd do that in the DA tables instead of calibrating the MAF to read leaner at a specific airflow. You want to be able to type an AFR into the OpenLoopMaxOct and be able to hit close to it, if not right on it. That comes from having a well calibrated MAF. It's much easier IMO to command a specific AFR than to guess with the sliders.

That makes sense, So I should zero out the maf sliders past what hz range?

you need to keep the mafcomp sliders adjusted to reflect how much air is entering the engine throughout the entire hz range your engine produces. you then adjust the maxoctane tables in direct access menu to achieve the desired air fuel ratio. .

Thank you EGL, I'll do some tweaking and see where it lands I had already jumped the gun and zero'd my sliders past 600hz but adjusted the DA table to reflect it, tomorrow I'll post another log. The good news is I did a pull with the sliders zero'd and I think I can reasonably adjust the mafcomp to get me about where I need to be as far as AFR goes.

In my original post I asked about IAT temperatures, what I meant was to ask about my Inttemp, I can't generally find a lot of info on that because it all comes back to people running SD, and I try not to ask a lot of questions because normally the answers are there, I just haven't searched hard enough, so any information is appreciated.

I did another pull on the way to work, I really feel like my horsepower and torque figures are low compared to some of the other guys running the same turbo, my airflow is right about 38lbs a min but the horsepower and torque figures are a lot lower then any of the other logs I've seen..

Following the pull I made some more adjustments, I followed the wb factor and raised and lowered the mafcomp sliders a little bit where it showed anymore then 2%

it looks like your tps needs some work...
have you tried the tps adjust tool?
start a log, don't start the engine, push the pedal to the floor, release pedal, right click on the graph, select TPSadjust from the menu, save the new setting to ecu, start new log and confirm you have 0% throttle at idle and 100% throttle at WOT.

your wideband and airfuelratioest are close to matching, but you need to do the tps work before proper WOT tuning can begin.

I found the culprit, my floormat (not made for my car) and I have to really stab the pedal hard to get a proper reading, I'll fix this before posting another log, and yes I have done the TPS adjust, normally I don't monitor it unless I'm going to post a log, should of paid a bit more attention on this one.

Instead of creating a new thread I'm just reposting my latest log here. I am now running an evo3 16g and fp2 cams

All boost leaks verified, made sure the car is mechanically 100%

The car runs very strong, but I just want to make sure I'm not leaving anything on the table.

The tune looks great overall. Your timing is pretty advanced for a pump gas tune, and AFRs are spot on. How much boost was this log on?

At this point, I'd try and add in a bit of timing, and bump the boost a bit until you get knock. I'm still not sure how you're managing 43+ lb/min on a 16G. I wasn't even getting that kind of flow out of a 20G compressor on E85 and HKS 272s.

I noticed you have the global scalar for the MAF bumped up a bit. Was your MAF off significantly across the board?

Overall, there's not a whole lot of room to improve the tune, which is a good place to be

That means a lot coming from you, considering I received ECMlink in October last year and knew NOTHING about it beforehand.

I am running 25psi right now, I am having more knock issues at low load/rpm then I am at the high end I need to lower my knock sensor threshhold and just take some timing out of the cruise area..

I think where I am at now is about as far as I can go with the 16g on 93octane, I can turn the boost up, and the timing way down, or switch to E85 and change my fuel system as needed.

My next addition will be a MAP sensor.. I can wire that into my EGR output since I deleted that right? I just need to figure out where to use as a source.. I'm not crazy about drilling and tapping my manifold at this moment as I need to take my other car and tear it down for a few days.

Yeah, you can wire it into the EGR input. You can tee off almost of any manifold boost source you already have running.

Then I shall get a MAP sensor and stop being lazy. Thank you

Cruising and idling, switching my deadtime over to the DA table. I'm trying to figure out why I wasn't knocking at 25psi before but now I'm battling it pretty good. I'm wondering if my "bleed" style mbc has something to do with it.

Oh got the map sensor, just haven't had a chance to wire it in yet, that'll be tomorrows project after going to see Emery at STM
