LinuxRacr's Haltech E6X Log..

No man... it's really simple.. you just have to get the correction maps right.. then it's golden.. you go through this ONCE... after you have all the correction points lined up you are all good to go and the car will run regardless of conditions... it's tuning... plain and simple tuning. Nothing big about it.. nothing hard.. just a matter of making the adjustments and getting it right... that's why people like Ken and I are happy to help.. we've been through it and know what it takes... and once you do it once it's easy to do a second time.. .

It is never that simple when you are dealing with bigger injectors. Most injectors will not spray correct when the pulsewith is cut down to far.

Next time you take a shower look at the water coming out of the shower head. Start turning down the water and you will see the spray pattern start to go the s***. The same thing happens with a fuel injector.

It becomes a fine balance to some extent between fuel pressure and duty cycle at the low end. It can also be compensated for by slightly raising the idle... say 1100 instead of 800 like is stock. There are always ways to get around it... the other side of it though is that because of the poorer spray pattern you get slightly worse atomization... which in turn requires more fuel to be sprayed, and thus you get to run a longer open time which helps... it balances out reasonable enough that you can get it to work just fine. But it is more touchy than a small injector.. doesn't mean it can't be done effectively though. It's one reason dual banks is helpful.... but that is an expense and trick in itself.

Fiddling with the fuel pressure to get an ideal base pressure is also another option.
 
If cold start was truly an issue of big injectors than Supra's, Evo's, and dozens of other cars running over 550cc injectors would all suck in the winter... obviously that is not true...

Hell for the truth of it Keola had "cold start" issues with his stock injectors with the Microtech... at 70F. Obviously it was the tune and nothing more and has been corrected... but it doesn't change that he saw the same sort of issue as Linux... and at 70 degrees with the stock injectors.

Cold starts are just tuning.

That can be said again..I dont think anyone ever said that bigger injectors dont work for cold start, I just think the consensus is that they are much more difficult to tune for cold start..what we seem to have here...Anyway, I for one am totally glad to see Pat's car running well for once, and I kno youll get the cold start worked out shortly..
 
Well, it was about 6 C (about 43 F) outside this morning, and I was able to get my car started after getting another jump so that my battery was strong. I'm upgrading to the Optima Red Top TODAY! This will eliminate THAT problem at least. I just went to lunch, and before I left with a co-worker, I went to see if my car would start. It started right up. I let the turbo timer keep it on while I left for lunch. I made some adjustments to my Fuel Air Correction map while cruising on the highway at warmer temperatures. I was dumping too much fuel in at cruise. I figured I would give this a try. Comming back from lunch an hour later, I went to see if the car would start. It started right up. I think that the adjustments I made helped. I was having trouble starting the car at warmer temp readings mostly.

On a side note, on the way to work, I turned the boost control knob up again, and was running 10 PSI. All I have to say is HOLY s*** BATMAN! (eek2)

You cannot compare apples to oranges, they were designed for turbo and have so much support. I'm sure you can tune it for smooth operation, but not like stock.

Linux--good luck, get that thing running and lets see some numbers of what it does, so I can try to beat them.(glare)

Started it up again! Bonus! How long is this gonna last?

patrick i sent you an email about the xenarc you ordered from me and bryan. also, what kind of changes to the air temp map did you make?

It will run good enough when the tuning is done. That is what I am hoping for. Stock ECU's are so advanced these days...so advanced that they are like A.I. :eek: I look forward to putting down some decent numbers soon. My goal is not to be one of the fastest, but one of the most reliable fast Proteges. (second)

I made the changes in the warmer ranges, where the air temp is high after the car is sitting after warmup, and the car is off so that I can start it back up.

cant believe you misspelled my name Cen.

Yes with OEM systems they run 520cc for the STI and 550cc on the EVO. They also have intake manifolds that are made for the cars that work well in keeping the air speed very high across the injector tips. They also have the fuel pressure controlled by the OEM computer. They also pass all emmisions testing and they idle around 600 to 700rpms. What aftermarket system do you know of the can get all of this done?

Right... that's why I say the OEM computer has the superior tune. But a blanket statement that you can't get large injectors to create a good idle is false. That was all my point was.

at least a mod owns the thread and can clean it out...

That's right. If you have questions about my experiences with the Haltech E6X, or want to read about how it's working out for me, you are welcome to post, but if you have other topics like injector theory (big vs small), and un-related s*** to discuss, then get on AIM, or make another thread. Stay out of here!
