Chipped?

[rooney77]

Well I had a family member who has a late 99 as well, drive my truck yesterday. Before he even pulled away from the curb he asked what chip I had, of course I replied none. He said there is no way that my truck has stock tuning. This excited me at first since I got to thinking that means I don't have to buy a chip. But then I remembered it's been running the stock airbox and stock exhaust with no gauges. I'm hoping it hasn't had the egt's get too high. Anyway, is there a way to locate the chip if it has one? My only other concern is that it could be a programmer tune and the previous owner didn't de-tune it before taking the programmer with him. Which would be lame since the programmer is more than likely still vin locked, but it also means (I assume) that I have no way to go back to stock or change my tuning. So would a chip be between the PCM and the big plug on the firewall? Is there anyway I can determine what's been done if there is no chip?

Take out the kick plate by your left foot. The PCM will be right there. There's a little black plug, cover thing there. Pull it off and look. If you see the computer board there is no chip.

If you see the black cover on the PCM, there won't be a chip. Like you said, if the previous owner had a programmer on it and took the module with them, you'll have to get your pcm reflashed. I'm not sure on the price of that, but I know on a Dodge it's about 100 bucks and some change.

Look under the hood also. There were/are some models that plug in out there too.

You would check the ICP and MAP sensors for anything else plugged into them.

There's nothing that I can remember plugged into the MAP and I have no clue where the ICP is located. As for the PCM, you can see the silver box, it's got no cover on it, but on the end opposite the firewall there is a black plastic piece that feels like it's just slipped on there. Being a 99 I figured if it has one it's in between the PCM and the harness plug. I just need more hours in the day to get to it. I'll try to look at it this weekend, I'll already be working on it putting in the 2nd Ibeam bushing, exhaust and attempting the ccv mod.

Take a picture of it... and post it.

You should get yourself a set of gauges if you tow alot. Otherwise you are probably just fine...

ICP is over the drivers side valve cover by the alternator. You don't have a chip in the pcm you could possibly have had a programmer on it though.

I don't tow anything yet. I have to finish building the rock crawler before I get to that point, which will never happen if I can't quit spending money on the truck. I'll try to remember to get a pic this evening. I may just take it out while I'm at it since I'm not driving it at the moment.

Yeah take a pic and we can tell you if there is a chip in it

Could be just a simple 10K mod too. Check the ICP and see if there is anything(i.e. a resistor) sticking out of the plug.

Try this too......if you stomp on it from a stop, and see what your 0-60 time is approx. If it is chipped, you'll probably be somewhere under 11 sec.

I wouldn't worry too much about your egts if you haven't been towing, and the truck is otherwise stock.
