I am starting a new tune (first time).

http://www.efidynotuning.com/scaling.htm

I am in the scaling sections and trying to figure out how to scale my injectors? High / low slope and breakpoint? I have Deka 60# injectors.

Also, how important is the AIR_MAN_VOL function? I have no idea what my volume is. Its a "Speedmaster Shootout EFI" manifold. Carb style intake with an elbow for the intake pipe.

follow the details in the scaling write up

air manifold volume has nothing to do with the actual intake manifold, its the modeling for transient fuel, you can leave it be until you get your tune dialed in

OK so I went though everything with I believe was a fine toothed comb. Using your T4M2 tune, I adjusted values to scale properly.

The car starts, but its very rough (as to be expected I suppose). I made a simple gauge screen in TunerProRT so I could attempt to see whats going on, but most of the gauges dont work. I assume I have something wrong on the software side? RPM, ECT, ACT, MAF Voltage, Battery Voltage, TPS... All don't change and read wither 0 or -2.

The title bar of Tuner Pro reads... Is the XDF and ADX correct for a T4M0 ecu?

TunerPro RT - T4M3.bin | XDF File - CBAZA_181109.xdf |ADX File - cbaza_181112.adx | XDL File - garage.xdl

Added the tune file and the data log. The log is just me starting the car in the garage for a few seconds, not sure how much or if it helps at all.

Tuning is kicking my ass right now.

If you are asking if the .bin patched, then yes, it is.

I changed some of the gauges around and I was able to see a few more things. RPM being the one I was shooting for (just for a sanity check that things were working).

I have attached another test start (test2.xdl)

After the car could barley hold an idle on its own I hopped out just to check things out and noticed the drivers side headers looked really hot. Just bumping the throttle plate with my hand I was able to see the drivers side header start glowing red, while the other side did not. What in the heck would cause one side to be worse than the other?

Do I have a plugged up fuel line maybe?
Is the ECU capable of changing the fueling on just the drivers side injectors??

Any tips where to look first? I'm using the T4M2 base tune.

u need to verify timing

verify tdc with a piston stop and verify the balancer matches / hasn't spun

verify base timing is 10 dbtdc with the spout out

Sometimes you just need that extra smack in the head form someone…

My balancer has 3 sets of timing marks, I timed the engine to 10°… just the wrong one. I was probably 40° ATDC. I noticed this after manually checking TDC with a piston stop. Thanks!

I popped my old chip back in and badda-bing, fired right up and ran.

SO, I’m on the road again (on my old tune) but I still want to dive into this tuning wizardry. Thanks for pointing me to the right sanity check. I’m sure there will be 1,208,330 more questions regarding the tune.

Update:

I plugged my QH back into the car and started it up with my "T4M3" tune that is based off your custom tune. Car starts and runs with some help, and will hold a rough idle decent once warm.

I have attached the data log of the warm idle I was able to produce.

I do not have an IAC currently wired in. However, using the "NUBASE" function I am able to change the idle. It can make it to about 600RPM before it coughs out, and up to around 1000RPM (it wont take anything more than 1000RPM). How is the engine able to control the idle with no IAC wired in?

On that same topic, does anyone know which prong in the IAC gets the signal wire and which prong gets the +12V? My new connector just has 2 white wires.

Step by step, piece by piece, getting there!

I got my IAC valve wired in and its working. It surges the idle a bit, but I assume thats to be expected with a base tune.

The video below shows the idle at a warm engine temp. The "wideband AFR" and "wideband Lambda" are actual readings coming from the MTX wideband gauge I have installed in my car. The LAMBSE gauges are direct from the ECM.

Few questions:
- Which HEGO is the correct one to be looking at? I assume HEGO2 as it is the one jumping above and below 0.4v
- After a rev the engine, my LAMBSE1 goes to 0.750 and stays there for exactly 1 minute. (video time 1:11-2:11 and 2:42-3:42). I'm just curious why it does that. What parameter sets that 60 seconds? Should I change it?

https://www.youtube.com/watch?v=3PleL00 ... e=youtu.be

Next up is this graph I made using paused data points from the data log. I did a few data points at each step where I held the throttle at roughly 1,000 rpm increases. It looks like the actual LABMBSE and the lambda read by my physical gauge are at least linear to one another. This means I just need to get my MAF curve and injector slopes dialed in correct?

surging idle is usually due to fuel not dialed in

u have to look at both hegos as they are each bank

if it goes to .75 lambda then the hego is reporting lean and the ecu is adding fuel to get it to switch, nothing u can adjust for u need to dial in your fuel or fix your hego issues

yep need to dial in your fuel

Any reason they are reporting such different values? Just a bad sensor?

So next step is to follow your write up on dialing in fuel with low load street driving and dial in the MAF curve and tweak the injector slopes to make the LAMBSE1 and 2 to match my wide bands lambda reading...?

u have to determine that as the tuner, if the banks are far apart u need to investigate check for misfires vac leaks etc...

if u have good injector data dial in the maf
