just got chip installed!!!
Hey everyone, I bought a performance chip for my 95 LS a few months back. Since the day I installed it, it never worked. I finally got in touch with the person I bought it off of and he told me to send my ECU to him so he could install it for me. i thought sure, sounds easy enough right? Well after the shock of the shipping prices (next day air sucks) I thought it was done, over with. Well turns out my ECU had a section of it that had been burned. My new mod had now become a hobby. The company I delt with (Tru Motorsports)was really cool about it, I spent an extra $125 and got a completely new chipped ECU, and I also get my old ECU back fixed and chipped as well. So when I plugged the new one in and turned the key I knew it would work. Got out in the street and went tearing up the road. The power is amazing, a real noticeable difference. The chip claims to add 10-20Hp, I think it added between 10-15Hp to mine. Thought you guys should know that chips are woth it to get, my only advice would be to get it professionally installed the first time!

Why will an "off the shelf" ECU Disappoint?
The first reason is that on most naturally aspirated engines operating
on pump fuel, the only way to achieve tangible power gains is by
increasing airflow through the engine. Chips cannot do this therefore they cannot make much difference in power output. Chip re-programmers can richen the mixture slightly at full throttle and advance the ignition timing slightly perhaps but this would be at the expense of lowering the factory safety factors for detonation and emissions. The absolute maximum gain in this instance would be on the order of 5% and could be as little as 0%. Most independent tests that I have seen on performance chips for naturally aspirated engines have indeed shown minimal or no gains in acceleration.
Some were slower than the factory chip.
Chips for use in factory stock turbocharged applications can increase
power substantially in some cases by raising the boost pressure. This
again reduces the factory detonation limits and you risk engine damage.
Without increasing fuel octane, you are asking for trouble especially if your engine does not have a knock sensor.

Ok fellas, I bought the chip off of ebay for $100. He was selling both PYR and Spoon chips, I think I got a PYR chip. What you have to do is unsolder the spot where the Chip and rom chip will go. If you don't know what your doing please don't try it yourself. Most of the time with the ECUs, if you try to chip them once, you ussually can't do it again. I will be getting my Old chipped ECU bacvk in a few days. I will be selling it on ebay if you want to look out for it. If you buy the whole thing, all you have to do is plug and play!! Check out the picture for the installation spots.
