3.1L/3400 hybrid swap.

[fasteddi]

Updates if anyone wants to know. Ran it yesterday. Soild 8.07-8.12 1/8 miles. Won my first round with a 12.59@100mph on the brakes dumping at the end for the win on a 12.49 dial in. Their timing system died so we all split the SPT pot and called it a day. Too bad because I wanted to win some more Pts.

Cars running great. Didn't want to change anything as far as the tune as its solid, conservative, and nice and consistant.

ok i tried setting the wires like 165432 and the car started

The coil packs are 1,3,2 in order... IIRC, the end with the 2 connections gets the #1 coil and the other end gets #2.

[QUOTE=charleszona;470092]i had tried 123456 but the car wont start rather rough idle and stop and the coil pack numbering, facing the hood from right 3/6 5/2 4/1 this the numbering from right to left

how to reprogram pcm in oldsmobile silhouette v6 3400 1998

[caffeine]

From left to right it should be 1/4 6/3 2/5 sounds like two of your coils are switched

[charleszona]

ok so i should inter switch 2|5 6|3 right

[charleszona]

caffeine can still tell how to reprogram pcm for silhouette 1998

Why is this completely unrelated string being posted in fasteddi's thread? I come here to read about fasteddi's progress, not someone who can't figure out why their (unrelated) engine won't run well.

ALL, absolutely every, no exception 60 degree v6s in this GM engine family are firing order 1,2,3,4,5,6. If placing the plug wires on the properly placed coil terminals is not working to have the engine run well, then you have another problem and should likely start your own thread about it, instead of mucking up someone else's thread.

Update 21 Passes later the car is still running good. Solid 12.50-60 car at 13psi. Love the hybrid setup.

How much of an improvement over last year?

How much of an improvement over last year?

Well I picked up about 7mph average on trap speed at the same boost level as last year and picked up a solid .45 of a second on the 1/4 mile time. The tune actually has less timing then last year, but about the same boost. 13psi

[unchained01]

Would you attribute thast to track conditions , your foot, or changes in weight to the car ? Sounds like a nice improvement overall And getting it dialed in I always nice !!

[fasteddi]

Track conditions are always good where i go. This year so far ive only taken it out on days where the DA is average and not very good/hot humid days. Im excited for some cool fall days.

The top end hybrid swap did all the work. The car actaully pulls very hard down track now. Before once 5k rpm it would start to slow down and you could just tell that it was restricted. The higerh compression compared to my prevous, the tube headers compared to last years log headers, the dis, the intakes, and aluminum heads, all helped to make the car have a better overall combination on the RPM areas where I use to lack the power i wanted.

[fasteddi]

Little update. 37 Passes to day: New best is 12.25@114mph. Finally got a 7 second 1/8 mile time. Running 14psi of boost now but still footbraking.
