Superchip question for Mike T.
Mr. Troyer,
I purchased a superchip for my ranger from you several months back. My chip is working wonderfully, but a friend's chip is not.
He has a 1998 Ranger 3.0L/5 speed. After he installed the chip, his engine started pinging under acceleration (he uses 93 octane fuel). He returned the chip, and superchips retarded the ignition curves a little. After he got the chip re-installed, the engine continues to ping under acceleration. He really wants a superchip, but the chip isn't working properly.
His other mods include: KKM Tru-Rev intake and flowmaster 40 series muffler
Any help is greatly appreciated,
Thanks in advance,
Jim Lee

Dear Jim,
Talk about timing!! I just a few minutes ago got off the phone with Superchips, and this exact subject came up, believe it or not.
Some of the 1996 & newer (OBD-II EEC-V) Rangers need to have a little bit more fuel added to their programming when you open up both the intake and the exhaust like that, as every once in awhile you'll find a Ranger go a bit lean, just a tad outside of the total effective compensation range of the O2 sensor system. So they'll exhibit detonation, not as a result of too much spark advance, but from going a bit lean. This is something that typically is a consideration in turbocharged gasoline engines, for example.
Detonation can occur not only from too much spark advance, but also due to a lean mixture, and a couple other thigns can cause this too, so it's not always a matter of only spark advance.
My wife's Ranger, a '99 4.0 model, has the Tru-Rev induction kit on it, as well as a good cat-back exhaust system and the "standard" Superchip for her Ranger's computer code, and we do not have any problem with detonation, ever. But this is something that we have seen come up on a few Rangers that have both the intake & the exhaust opened up. The Superchip itself is probably working fine, its program simply needs to be adjusted to fatten up the fuel curves just a bit, I'd bet. Just have your friend contact Superchips, and have him ask them about this, so they can take a look at this possibility.
Another possibility can be that the actual energy content of the gasoline he is using is a bit too low, even though the octane numbers are there. Just to give you an idea, the rated power gains are made using the 92-octane pump premium gasoline available in the greater Orlando (florida) area, where Superchips is located. So 93 is plenty of octane, it sounds to me like it just needs a bit more fuel for that particular truck, as they can and do vary a bit in those Rangers.
Feel free to give us a call about this if you like, and good luck!
