First shot at tuning cable TB and bigggggg cam

[mowton]

A buddy called me today and said he was having some issues after he installed a rather large cam (250/260 on a 110), fast 92/92, headers and I believe 42# injector. will check all this out tomorrow. It is a 98 Fbody automatic and while I am looking at the results of his day......wondering if you guys with large cams could add your 2 cents as well. I won't be able to get a scan til tomorrow, but from what that said it appears to be idleing very rich.

He set some table during his troubleshooting so a few are blatantly wrong (i.e fixed adaptive idle timing to 28, idle overspeed, Base Spark in Park is too high and open loop EQ is all set to 1.0). I am not that versed at IAC ( I have a 2004 C5 ETC) so I will be learning as I go.

Thanks in advance

As he suspected, there was alot more going on. The Fast 92 was installed incorrectly (didn't use button bolts) and cracked the bottom plenum.

Thanks anyways
