Hello
I have a surge while cruising.
Vehicle is a 1971 Chevelle Ls3 4l80e BTR Stage 2 V2 Cam.
I calibrated the MAF and VE LTFT below 5% and smoothed the ignition table.
But I still have a surge at 1500rpm when cruising.
You can see it in the last third of the scan
Can you help me or have another idea ?
Thanks for Help 1971_Chevelle_LS3_4l80e_BTR_CAM_Final.hpt1971_Chevelle_Ls3_4l80e_BTR_Cam Probefahrt cruise.hpl
