Can I get some eyes

[srobertsfsj]

Hey guys, been a while. I finally got my Jeep back on the road and made my first offroad trip out to Ouray, CO last week. The TBI performed much better then I expected. However, I didn't get a chance to do any tuning before I left. While I was jeeping I noticed that the Jeep was running a little lean, which it wasn't before I left. The only thing that changed was I turned on EGR and the AIR Diverter settings so I am assuming this is why it is running lean since the recommendations I have seen is to turn off EGR when tuning. Anyway, I made a nice long tunning run this morning before work and got that inputed into the bin.

What I need some help with is trying to figure out where my top end power is. Driving on the mountain roads to get to the trails I noticed that I was really lacking in power trying to get up some of the hills. Much less then when I had the carb. The tunning run I made this morning had some highway hills on it so I was hoping that I can get a more experienced person to take a look at my log and bin to see if I am missing something. The fuel pump and alternator are brand new so (for now) I am assuming its not a fuel pressure or voltage issue. Let me give you a little background on the Jeep:

86 Jeep Grand Wagoneer
Engine - 2bbl AMC 360 with mild cam
Axles - 4.10 gears
Tires - 35" KM2 MT's
Fuel Delivery - Brand new In-tank fuel pump from a 90 Chevy pickup in a 33gal tank
Optional TBI sensors used - VSS, EGR, 7-pin HEI
XDF File - $42-1227747-V4.3.xdf
ADX File - $42-1227747-V4.2.adx

Thanks for the help!

Also, I just noticed that when I paste my new VE table into the bin and click save, that the new values are not being saved. I thought I remember this happening before but I forgot why it was doing it. I clicked the save button for both the parameter and the bin file...

Nice work on the added history tables!

But I think we are going to have to change your name to "Sparky" or "Knock" ... first thing I would do is not run engine anymore, then pull the spark plugs and use a magnifying glass and look for specks on the plugs!

[srobertsfsj]

I turned the knock off awhile ago. From what I understand the AMC engines are noisy.

[EagleMark]

OK but your spark advance table looks more like an LT1 then an AMC... 35 degrees at idle? This looks like a 454 bin to start so warm spark bias is 0, now if it were 9.84 like a 5.7L bin you could be OK. But you are still adding 2.11 degrees PE spark and 5.05 Spark slope which puts you into 42 degrees advance in some areas of acceleration!. Your spark table is already very high without these adders.

You really have me worried here!

Take out 10 degrees from your entire table and see how it runs, this will also give an indication of real or false knock counts from first log.

I will give that a try, did you see my comment above about tunerpro not saving the VE table? I hit save, it closes the parameter window, I open the table back up and none of the changes are there. :(

[EagleMark]

Yes but was very concerned on spark table after I was watching knock counts.

Are you trying to add VE1 and VE2? They will add up to over 100 and be cut back to 99.6. Or sometimes it is adjusted to an acceptable hex equivilent but close to what you put in. If your trying to paste an entire table it has to be exact as table being pasted too. What exactly is happening?

[srobertsfsj]

I am pasting the whole table from the VE Correction spreadsheet into the "VE as % (FL1) *Same as above*" table. This is how I had been doing it before and it worked fine. I dont think anything adds up to over 100. all the columns and rows match the spreadsheet to the parameter table.

Just probably the way you are copying the table. If your a little off it does not work. In spreadsheet try clicking on right bottom cell, then hold shift key and click on left top cell, this will highlight the entire table, copy or Ctrl C, then do the same in TP VE table and paste or Ctrl V.

[srobertsfsj]

ok figured out my screw up. I forgot to paste the current VE table into the spreadsheet, I had only pasted the BLM table. It's save now, thanks Mark! I will give the new spark table a try and report back, anything else you see wrong with my bin? The reason I set my base idle to 10 is that I just cannot get it to idle right if I set it to 0 deg.

[EagleMark]

Didn't look to hard other then that? Try above, also may want to put a timing light on it and see where timing actually is at timing marks and compare to what data says?

Do you have a large cap HEI distributor?

[srobertsfsj]

yes I am running the large cap with the 7-pin module.

[EagleMark]

Then you spark latency is also wrong and timing can be as much as 11 degrees off as well. Do you have a GM EST module or aftermarket? If you say aftermarket just get a GM and tell me GM...

[EagleMark]

Here is the GM spark Latency table for $42, although it never came in $42 bin files.

 0.00
0.00
213.64
274.68
305.20
244.16
274.68

320.46
289.94

I put it in your bin for you so you can compare.

LOL, I believe its an ACCEL module, does GM make a 7-pin? I went with the 7-pin because I couldn't figure out how to make stock 8-pin work with the HEI and I couldnt find any diagrams.
