Your exhaust system may consist of a manifold, and a series of pipes, muffler(s), catalytic converter and exhaust tip, all designed to scavenge the hot exhaust gases from your engine out to the open air.
When you locate the file, right click on it. A list of options will come up. There should be four items, including restore, cut, delete and properties. Be aware if you select delete the file will be much harder to recycle catalytic converters locate after this point.
BPU(TM)’d Supras run a little on the rich side as far as fuel ratios go. This hurts power. What it does do is provide a safety margin that makes engine damage through detonation unlikely. If you get a fuel controller, and tune it properly (on a dyno, with an accurate EGT gauge, and a high band O2 (The Stock O2 sensors are not accurate), then you should be able to gain a noticeable amount of power. One of the most popular electronic fuel controllers is the A’PEXi S-AFC. The Fields SFC is good too.
Plain and simply for the monetary incentive of getting cash for your old mobile phone. Studies have shown that statistically around 80% of people would only recycle their mobile for money or some other incentive. Fortunately this is the case for working and broken phones alike. And you can even get Gift Vouchers for mobile phones now.
It’s a good idea to retrieve deleted files from scrap O2 sensor recycling bin quickly as the space the files took up is now free for other files to move into. If you wait too long, the files will be replaced eventually and will then be considered unrecoverable. However, if the hard drive has a lot of space on it the files will be kept for quite a while.
Unfortunately, things start getting more difficult after simple BPU(TM) modifications. Modification becomes more than “bolt on Downpipe, gain 50hp”. Things like tuning, parts selection, and matching combinations of parts become much more important. However, this is the case with ANY high HP car. Actually, even at exceptionally high power levels, the Supra TT is still easier to extract power from than almost any other performance car. But it should be kept in mind, that it wouldn’t be as simple as the BPU(TM) bolt-ons.
It is not uncommon for us to make mistakes. We forget or unknowingly delete files. Retrieving files is a thing of the past. Thanks to data recovery software and tools.
