Heres a little update on how well my MP3 is running since the switch back to 91 octane.
Ive been running on 91 for 3 tanks now and either I've gotten used to driving an actual car or the performance has declined. So yesterday I decided to reset my ECU. Then I did a little conservative driving. During the first trip, at idle the engine seemed to want to stall. After a day of regular driving, I noticed that the idle was smoother than before the reset. Its easier to put it in to 1st at low speeds. While driving at varying speeds under 10 mph, it doesnt jump. The engine felt and sounded smoother across all rpms. The engine sounded less rough and quieter. Starting up in the mornings and in general is better, easier. It doesnt seem any faster. In fact, it seems less torque-y. But the engine sounds and feels more comfortable especially in the high rpms.
I have to admit that I thought that the whole reset the ECU was b.s. But I like the way its been running so far.
This may also completely change the characteristics for those who only run strictly 87 or 89. If anyone running 87 or 89 can test it and let me know, thatd be great. And if you could come in on Sunday, too. Yeah, thanks.
- For those who want to know how, but dont want to search the boards <font size=1>lazy bastards</font>, all you have to do is disconnect the negative terminal connector for while I did it for a minute. This resets the ECU & the radio & any other electronics. Then I let it idle for about 10 minutes.
but nothing major, ever)
. 87 won't hurt a thing. I believe the book says that less than 91 will result in reduced performance. I believe it will just retard the timing a bit. I'd be interested in a dyno run on the two types.
