Engine Analyzer Pro

Group,

I downloaded a demo copy of Engine Analyzer Pro (the mid-level, $200 version). This looks like a great way to predict power changes from modifications and I will probably purchase the program. As I understand, the power prediction may not be absolutely correct, but the benefits are being able to predict the relative changes from modifications.

Is it politically correct to ask if anyone using this program would share basic parameters they have loaded for a 2 liter, single plug, Spica injected engine?

Thanks,

Since when has "politically correct" had any place at this forum? Seriously, I use this program and I like it. I've tried a couple others but I keep coming back to this one. However, I have only worked on the 2-L twin spark with it so I can't send you any data on the classic 2-L engine. If I had it, I would. I just sent "Craig" my settings for a stock TS . I didn't spend much time on them because I'm not particularly interested in the sotck TS. The data are actually just guess work but the bhp and torque values it produces are within about 5% of factory claims. One word of caution, while I haven't worked with the forced induction part of the program, in a brief discussion I had with Jim Steck about a year ago, he indicated that the absolute numbers from that part of the program were very optimistic.

Most engine tuning programs have a tough time with boost, BTW... The ones we use here at work (F) struggles big time with boosting. There are a TON of odd variables that changes a lot- exhaust pressure, intake pressure, and overlap - just a mess.

George, call Jim. I'm sure he has some data.

Bugs

I feel I should pass this along just to let everyone know; EA Pro is not bug free . It is prone to crashing if you try to use it in metric unit mode. It also occasionally does some weird things when attempting to overlay graphs of different engines. Finally, I've noticed that sometimes it loses track of the engine I'm working when I use the optimize capability accessed from the main menu. It just seems to substitute some previous engine when I exit the optimizer. Still, it's the best program I've tried so far. If someone can find a better one, I'd love to hear about it.

Not super relevant, but just wanted to let everyone know that sharing this kind of data is perfectly legal. Even politically correct, as you are doing a service to your fellow enthusiast. There is no intelectual property associated with this kind of exchange.
