New chip

[Tim Hensley]

Going with the 5.7. Because it gives Me 1st gear  WOT fuel. And 1st/2ed  timing in cell 3.
This is cheaper than a converter.
The converter will flash all over but I understand it’s different power I’m throwing at it.
Car pulls hard after the 1/2 shift and back half of track moves really good.
I have never got past the low gear fuel and timing just think how it will go after I get fuel and timing in high gear.
Took it to a dyno last Wednesday to get a hp and torque numbers for reference. Left with more confusion. Wanted to make sure I wasn’t going way past it’s cam efficiency.

See if they’ll print you a copy of hp/tq with mph instead of rpm then it’ll look more normal

you might try setting the 1/2 fueling to a leaner AF and see if that helps you get out of the hole better before you spend more money?  If leaning it down gets a better 60', then you know you are on the right track before you spend more chip money


the alky version of 5.7 might help?? 

[Tim Hensley]

This is my 11.1 A/F setting in 1/2 and 10.8 3/4,same lousy 60 ft with rpm drop and flat line at 30 mph, after looking my KR was at the shift of 1/2 not the end of 2ed. I have no idea why it was having such a hard time tracking. My one and only try past 11.0 (11.0 no help) not much KR but it scared the hell out of me.

Tim, can you post the file.

[Steve Wood]

Not sure that is detonation? Has the reverse characteristic s to detonation with regard to shape of the curve.  Looks more like wheel hop or a bump in the track or car suspension? ??

Insufficient data either way-need the file as Brad said and still might not know

[Scoobum]

WB not tracking correctly could be due to a faulty WB sensor. As Eric says. Junk in...junk out. I've seen a ton of times where the WB sensor is fukd.

Is the wideband wired directly to the battery and configured properly?

[Steve Wood]

I am pretty sure that is not detonation.  Strange that when the car goes to second, the mph barely changes for several samples while the rpm continues to accelerate.

Eric is really good at getting his chips close and one can usually spot a bad sensor by looking at the blm correction above the blm matrix on PL.  If it is off quite a bit (showing a big correction) then one can suspect the sensor.  
the Bosch sensors ain't worth a plug nickle.

[Tim Hensley]

Ok you got me thinking scoobum has said more than one WB not jiving with NB.
Dyno shops 02 didn’t agree with mine ether. I don’t know just how it’s wired, but I mostly follow instructions from manufacturers. I keep adding to the fuel correction window to keep BLMs close to 128. You may be right garbage in garbage out.

You found your problem. 
does it read 14.5ish @ idle?
