Tach flutter with Progressive Alky kit...

[TiClone]

I'm running, AFPR, walbro fuel pump, Razor's Progressive Alky kit, ultimate v7, ATR aux cooler kit & cat-back. Everything else relavent is stock: turbo, heads, cam, injectors, convertor.

I'm getting tach flutter around 4k rpm. The alky kit is stock out of the box.
Chip setting is t1-16. The Fuel pressure is about 38psi.

Can anyone tell me where I should start tuning.

I'm going to run a DM scan on it tomorrow.

Two things to check. One is on the SY/TY trucks, bad ignition system can cuase this. To isolate the alky kit, run a wire from the battery + or back of alternator to supply power to the red wire with spade terminal. 10-16 guage and use a fuse like 15-20 amp.

Some vehicles can sometimes exhibit scan tool abnormalities when using an AI kit.. not just mine. Worst case scenario has been running a relay switched power source from battery + or back of alternator.

Case in point is turbolink users can sometimes get abnormalities when power is sourced from fuse box.

Another solution posted on SYTY.net some time ago was adding a small capaitor like 470uf or 1000uf 16-25volt rated across the red/black wires going to the PAC. Not the pump wires, the power wires. If you want to try the cap idea, contact me and i'll send you one N/C.

If you need the wiring diagram for a relay switched power source email me.

Here is the simplified version, 5 terminal 30 amp automotive relay.

30 batt
87 PAC
85 GND
86 ign on fuse box.

Post back..ok

Hey Julio, can you send me the wiring diagram please?

And the capacitor, can I pick that up a Radio Shack or an electrical hardware store?
