I have no desire to get into a pissing contest with you on this forum.
1. No one doubts your knowledge of the OBD II system and its tools but I have had regular contact with several people in CA who do this for a living I believe they may have you beat.
2. I didn't say I got the HP gain from the temp drop alone. It was timing, additional boost and A/F adjustment supported by the Water/Meth system.
3. I have dyno numbers but dyno numbers don't mean **** to me. You want to race. Shut off your NOS and say where and when.
4. I stand by my comment about the A/F mixture. Rich is more conservative but the Water/Meth system alllows you to lean out without dentotation and my MSD DIS 4 also allows me to pull timing if necessary.
5. I don't come here to game or disrespect anyone (CLUELESS). Never have never will.
6. Name your race day!! After my surgery of course.
My LAST intention is to start a pissing match. I hate the HATE posts and certainly don't like to contribute but as I said, many people will read what you wrote and take it for gospel. "I gotta go buy a WI system for 7% increase in power!". I'd like to keep this in the open as an informational for others. If what you say is really true, post it for others constructively. I just don't want to sit back and watch wreckless, misleading info go out to lead others astray without challenging them. Sorry about the "clueless" comment, I watched it going too long and got frustrated...
1. I have worked with MANY people in the industry that tune for a living and they don't have me beat on OBD2 tuning... I'm not saying I know everything but I know enough to challenge that comment. Not a pissing match, just please explain how "the trick is OBD II Data". As I mentioned, all you're getting out of OBD2 info on the high end is the ability to monitor your timing.
2. Here is where I say your information is misleading. Additional boost has nothing to do with the water injection. Running the A/F leaner with WI is a common practicve because the properties of water and methanol give an almost infinite octane rating combined with the specific heat absorption allows for a leaner tune. Ask a little more about where you got the additional timing advance. I already know the answer and it has nothing to do with the WI and that is where the power came from. So if the power came from that combination, you shouldn't just tell people that the WI gives a 7% increase in power.
3. That's the funniest thing I ever heard! Turn off my N20? Get real!! I built my car the way I want it and it is built to take it. Post your 1/4 slip! I'm not saying dyno charts are the gospel but at least it is data rather than just talk. No dyno chart and no 1/4 mile slip= all talk...
4. How can you say you stand behind your statement on the A/F when it is a complete contradiction? You just contradicted yourself again when at first you said your "mechanic likes the safe side of A/F mixture where I will lean her out alittle more at the high end" and now you say, "Rich is more conservative". It doesn't matter if you have the protection of WI or not leaner is riskier, richer is safer... I agree WI gives protection to allow for a little leaner tune but that doesn't make it safer to go leaner.
5. Again sorry about the "clueless" comment, frustration...
6. Again on the race issue. I've never been in it to compete against any body here. I have my own personal goals with my car and it has nothing to do with how fast someone else's car is. Money determines how fast someone's car is. There will always be a faster car. I'm sure you have a ton of money in your car and can even spend more. That doesn't change any of the comments I made above and is really a distraction. Post your 1/4 mile slip... We don't have to get together... By the way, good luck with the surgery, I hope all goes well.
So the real story is, you have recently seen an increase in timing advance (so have I) and I know how that happened, completely unrelated to the WI. That DEFINITELY increased the power! The other increase in power is due to tuning the car leaner which you feel comfortable with because of the protection WI offers. That is where the power increase came from so others don't run out and buy a water injection system and wonder why they didn't get 7% increase in power.
My recommendation would be not to run the car leaner. Use the water injection only as a means of reducing heat soak in the sc. The only "good" spot to inject water/meth is between the MAF/AIT and the throttle body in the intake tube, perpendicular at a 9:00 or 3:00 position. By the time that mixture gets to the sc, it is completely evaporated there. I think running it leaner with that setup is still riskier. I would run the same A/F and just use the W/I for safety by bringing down the temp a little in the sc. -JoeB
