Foxbody Tuning Information

Unread postby decipha » Tue Jul 23, 2013 3:40 pm

The foxbody's have one of the crappiest tunes of all ford calibrations. It is almost impossible to properly dial in a bone stock fox without making extensive changes to the factory calibration. All of the foxbody ecu tunes are interchangeable, an A9L tune can be run on any foxbody ecu such as the A3M, X3Z, S0Z, D3D, A9P, A9T, etc... they can all be swapped with no problems. However, this is not true for those who use a Tweecer. The tweecer does not load the complete binary to the ecu so it cannot swap strategies. If you have a tweecer you must use your factory strategy "calibration type" otherwise the ecu will freak out.

I have made a performance stock foxbody calibration that I use on EVERY vehicle I tune. I have named it the A9L2, this is the calibration that Henry "should have" made.
All info on the A9L2 and the binary can be downloaded from http://info.efidynotuning.com/a9l2.htm

I highly recommend using this as your base tune to create your calibration, you, and your vehicle will be much happier from the get go.

I have successfully loaded A9L2 and everything appears to be working. I wanted to go check the ISCIBR payload per the writeup but nothing comes up when I Cntrl+F. Also after about 4 minutes of the car sitting here idling the CEL starts flashing.

Ipsibr isn't a scalar, it's a readout on the dash. Load the adx and record a log.

Yeah, I was looking for it on the dash but it wasn't displaying. Here is a warm start to full warmup to when the CEL starts flashing and for a few seconds. The ACT is pretty warm.

I'm not sure if I used the correct ADX or not.

Does anyone have any insight into this? Will I have to make a custom dash to get the ISBIBR to display? Any idea as to why the CEL flashes? I'm 100% green to this, just looking for some help to get some things sorted out prior to getting it on the rollers to get it dialed in. Thanks.

ipsibr is the idle air integrator its on the upper left side of the dash

a flashing cel means you have a fault code

pull codes to see whats not working correctly

That's what I assumed on both accounts.

I did a few searches and couldn't find a way to pull fault codes through Tunerpro. I also looked around in Tunerpro the other day and I couldn't locate any area that gives fault read outs. I have the ability to pull codes otherwise but is it possible to view faults in Tunerpro?

I didn't turn off the EGR valve after loading the A9L2... I wasn't sure if it is turned off or not in the base tune, honestly didn't investigate it yet, but I have that bypassed as the valve wouldn't clear my FPR. The fact that the CEL is flashing threw me off, as it doesn't do that in stock form... I assume that you programmed that into the A9L2 decipha?

Thanks for the help... I'm trying to not be too much of a PITA.

Roger. I honestly didn't even look at it because I'm a bit overwhelmed being new to the EEC.

I believe I have another on a stock TB. Thanks.

So no TPS codes but I have a code 41- ego not switching, lean bank 1 (I have a small exhaust leak on the passenger side, which is bank 1 correct?), 91- o2s not switching/ss1 ckt fault (seems to be a circuit fault?) and 96- fuel pump ckt open (this is a modified stock harness to fit into my 83 LTD and the fuel pump works fine). Also a code 15 but being it's a checksum... I'm not concerned.

Update: Cleared the codes with my Brick and ran it through a couple cycles and it is idling better than it was before. Haven't let it run long enough to see if the CEL stays off. Will clearing codes reset the KAM?

I've mended it... Ground wire in the wrong cavity on the engine harness for the O2's. O2's are switching properly now and exhaust leak is fixed.

Yeah, I fucked up lol

So now my CEL is coming on for a TPS issue. TPS reads fine upon cold start. Once engine reaches temp and I cycle the key it reads 1.25v idle and .75v WOT. I've tried both TPS sensors I've had laying around. I did not try a new sensor yet. I'm letting the engine cool down to see if it's a temp issue or not.



Jeremy

*Edit- It seems to be temperature dependent. After sitting in the car KOEO the ECT came down to around 120 and the TPS started reading proper. What is odd is both sensors do this...

Got the new TPS but didn't install it. Fired the car back up today and have been letting it run and doing some step tuning to the MAF and the TPS has been acting fine... I'll keep an eye on it but it seems to be just fine.

Is there a way to raise the ECT limit aside from changing the FN126? I have a mechanical fan and sitting in the garage playing with the tune the ECT is staying around 230. I understand this is a little high and that it will be lower once air is moving through the radiator but it seems to kill spark every time the ECT comes near 235 and the LAMBSE turns red on the realtime tuning dash and engine wants to stall. I also understand this is a safety feature and I plan on re-enabling this once I'm able to drive it when my driveshaft comes back from being lengthened. Thanks.



Jeremy

*Edit- So after almost an hour of running and playing with the tune the TPS messed up again. Plugged in the new TPS and still fuckered.

When you said the "two are completely independent" I assume you're talking about in an electrical aspect. I was thinking (and hoping) that the radiant heat in the engine bay/throttle body (using the ECT as a reference) was causing the issue in the TPS. A wiggle test shows no difference in voltage readings either. I'm going to check for shorts on the TPS wiring now as the voltages are reading wrong but I'm leaning towards the EEC being a concern...

BTW- Pin 46 is already grounded with the shields by the EEC.

Looks like it might have been an issue at the EEC connector. When I wiggle it it drops the TPS signal. It's all working well now. I'll depin it and fix the spread pin.

Here is a datalog... I can't seem to get the idle down. I closed the throttle plate about 1.5 turns and it still wants to idle around 950. Plus the timing is jumping all over... 14-30. Coming from a carb and from VE tables on the Megasquirt setup I'm kind of a stickler to know exactly where my spark is at idle.

the attachment is gone now with the forum ported over

2 things you want to check for

make sure the throttle position stays the same when off throttle

spark at idle should be aroun 14 or so

The TPS stays around .7-.8v at idle.

I drove it up the road today and anything past about 1/4 throttle the ECT goes to 240 and car falls on it's face just like it was in the shop?? I replaced the ECT when I first got the car running last fall. I took a snapshot but I don't think it will be worth looking at. I can post if it will let me. When I drove to the gas station to get some fresh gas today a state trooper decided I shouldn't be driving a car with no reggy, no insurance and no inspection... Luckily he let me flat tow it home and didn't give me any tickets. Oops!

I'm puzzled by the ECT reading going all fucky unless it is an internal EEC issue, which is probably likely.

.7 and .8 is a major difference, you need to make sure it stays within 0.02 volts every time it returns back to closed throttle

does the ect shoot up everytime you go half throttle even when the car is cold?

if it only does it when its warm it could be air in the line or its low on coolant / overheating
if it does it when its cold too then its screwy

the act and ect is also tied together internally so it could be a faulty act throwing it off too but just showing on the ect

KOEO TPS reads .74 then creeps up to .8 and remain at .8 through multiple WOT movements. The ECT stays with ACT on a cold start. ECT does not jump when going to WOT while running cold. TPS jumps around between .6 and .8 at idle.



Jeremy

Edit- I think slowbox is right, this TPS has had it. It is bouncing around between .81 and .87 at idle. What gets me is the spark advance keeps jumping around between around 14 and 24. Also with the TPS unbolted from the TB when the engine is warm the ECT still goes to 240 with a WOT hit when it is reading 215 prior to revving. I'm going to verify all of my voltages going into the EEC next.

I reloaded A9L2 to start fresh. Reset idle and started over...

Spark is good

TPS jumps between .82 and .88 very quickly but hangs around .88 mostly.

Idling around .96 VMAF at 900 RPM

I attached an idling snapshot. Is this TPS voltage OK?



Jeremy

Edit- Got it running a bit better and took it up the hill quick with just a breath on the throttle, runs fine. Turned around and laid into it a little and falls on it's face... I uploaded a new snapshot labeled Road Test. I'm really not sure what is the issue here :(
