Engine/Transmission (1998.5 - 2002) Smarty/ hot juice surge?????

[KKunz]

I have a 99 with edge hot juice and a smarty the trucks runs great on all levels except level 6(hot) the truck climbs in rpm to about 2500 then the slowly climbs to about 2900 then it reeves like it should. It feels like the truck surges and chugs in and out of power. Fuel psi 16 at idle no less than 12 at WOT. I had an edge drag comp and every thing work fine I have talked to edge and the sent me a new juice module but no fix any idea what is going on? Any one else having this problem?

check for codes

I forgot I had the power to check for codes

P0602

P1693

P0602-ECM fueling calibration error

P1693-DTC cleared in companion JTEC module



Any idea what the codes mean? This only happens on level 6(HOT) what is going on level 6 that is different than all the other levels?

I did some testing on my truck today the problem seem to get less as I go down in # on the smarty #8 is the worst and my problem completely goes away when I’m running stock software. The codes I had went away also when I put the stock software back in any idea what the conflict is with the two in level 6?

Any suggestions?

Surge

I recently had a surge at high speed with the TST. And was told to check the ALT by disconnecting it and running it the same way . It cleared for me it ends up that the Alt is sending a spike in the circuit and Digital electronics doesen't like spikes. D

The 0602 is code you get whenever you run a Catcher program and is normal. The 1693 code is likely of zero importance.
