How was my post "thinking lowly about other people"? I asked a very legitimate question which you have yet to answer...

The reason I cringe at the thought of a hole in the motor is because there isn't any smooth transitions in that fuel map and I truly think you should take baby steps in tuning this thing. It is quite obvious you still have a lot to learn.

I suggested reading that thread because it is VERY educational and will make YOUR tuning experience a better one.

But then again, I don't know anything... Moving along...

-E

P.S. YES, I did look at your datalogs.

 

^ you know well that I'm also know well that you were mocking me but that's ok. I know there're a lot to learn but I have no problem learning them. I did read that post that you mentioned and lot of other posts like injectors scaling and latencies. The reason I posted this thread here is maybe it'll help me and others who like to learn these stuffs. Sometimes, making some mistakes is one way to learn.

Did you look at my recent post with the rescale fuel values as suggested by some others? It's in post #24 of this thread.

 

You must be an expert at reading people on the internet. Now you say I was mocking you... which is the farthest thing from the truth...

Yes I saw your latencies/scalings. I still think they're off. Reason being...

Someone gave you the scalings/latencies of 780's and you still went about lowering the scaling number to high 500's. Let's put this in perspective...

When I bought my car in Cali, it had a tune on it with 720cc injectors so it was using Cali's 91 octane **** gas. The scaling is 609. These are smaller injectors than what you are using which leads to asking you this question...

Do you know that the smaller the scaling number, the richer and the higher the scaling the leaner? My suggestion is to put the scaling/latencies that were provided to you in the first place and leave them alone.

I am NOT mocking you. I am actually a pretty blunt person and actually love to help people learn. But what I don't like is people that seek help but will not budge from their thinking their **** don't stink when there's 20 people in the same thread saying the exact same thing to the guy seeking help.

^ now you said. But Wicked E, I did try lot of suggestion from other people with 780cc injectors supposely to be like mine, none of them work smoothly. Do you know that those settings not neccessay work for all cases. My car was throwing lean idle code, the LTFT fuel trim delta values were way off, I spend entire day to get it right starting from 709 and worked my way slowly down with combination of latency values and eventually found a good spot which, unfortunately not a good lean number according to you, at 597. It costed me almost a fuel tank to get it right with idle 10-15 minutes and running around to get the cruise trim repeately.

Wicked E, you know well that you quoted from GST post and laughing at people is a mean of mocking so don't try to act like a good guy. I accepted criticism but I'm not the kind of person that afraid to speak my mine.

 

I'm out of this thread...

-E

 

Wicked E, i don't feel good about arguing with you either.

 

OK apparently I have missed a lil bit here...
G20 Did you try the scaling and latencies I gave you??? Every car is different, but those were proven to be fairly close...

I dont think wicked was trying to get a laugh at your expense... Were are trying to help you out. A lot of ppl like wicked for example have been on this forum for a long time, and has learned what we want to know, and has been helping out newbs like us for quite some time now, and it probobly gets a lil old... Especially when you give him **** for it... I know since I have joined the forums, I have had to de-sensitize myself quite a bit.

I hope you would make it easier on yourself to implement the scalings/latencies I had given you and go from there... These arent made up from my bunghole, these are proven and pulled from the injector scaling thread...

^^ truth.

get ur injectors scaled properly then we can adjust ur AFRs to suit.

 

let push those misunderstoods aside. I'll help anyone if I can as well. I did that in here when ever I can. Sometime I'm just a little sensitive.

Ok! I started with a stock 05 MR map and scaled my injectors but the scale number 597 combined with the latency values that I found work best (starting from 709 and worked my way throught the LTFT as in the Injector Latency thread). My fuel trim is now -3 and -2 (Low and Mid), it should be good enough.

The scaling values that "nonscholont" refered for me is not working well for my case. Maybe my injectors are not "really" 780cc but I did spend an entire day to get it right (I think). There's at least one member in the "Injector latencies.." thread who had PTE 780cc had to scale it down to 597 similar to me in order for his injectors to work right.

So if you have any idea or though based on your experience please let me know, I'll try it. I'll be fine tuning the individual cell and WOT later this week when I have sometimes from work. I do notice that my car is running more smoothly now and using a little less fuel probably something to do with the scaling. Thank for all responsed to mine post.

 

Also get rid of the 3's at 4000

 

^ you mean the knock count? Yes I will. Usually I have to live with 1-2 knocks at peak boost since I'm on mbc and try running high boost. But 3 count I'll definitely get rid off.

By the way where did you see the 3 knocks count? I looked at the log and only found the max is 2 at 3700-4000 rpms with 100% throttle. Thanks.

 

G20 What people are concerned about is the abrupt changes in the fuel map from cell to cell starting at the 100 load region and going to the high load cells( 260 ) . Also you are going leaner in the very highest load cells ( 260 range ) than you do in the lower load cells.

It is not a good idea to go leaner in the highest load cells. These should be richer to be safe. If you run several pulls or run real hard for a long time, or overboost, you might run out of fuel up top and it will go way too lean = Boom = new block

So you need to smooth the target AFRs tapering to slightly richer the higher in load and RPM you go. This helps ensure your AFR is pretty constant when you change from one cell to another, like when you momentarily lift then hit the gas again.

24 on 91 octane is a lot of boost. Have you kept the boost load limit set to ~ 260? I'd make sure the overboost timer is not disabled either 1000 msec or less

I hope this helps a bit.

^ yes i did keeping the load max limit to 265 for now. From 7000 rpm up, I target my AFR to 10.9-10.8. Do you think that is good enough?

I did tested the momentarily lift and hit again as you mentioned to make sure my AF is ok and it appeared to be on the rich side (below 10.9). It's a lot of work but I don't mind, it's my car anyway so the beauty of tuning your own car is you have all the times to do it.

Your suggestion helped me ensure my thoughs. Thanks.

 

Why so rich?

 

^ from 7000-7800 rpms I just want to be a little safe on 91 until I feel more comfortable with the way the car running and maybe bump it up. For the between shifting that AF drop to 10.9, probably those cells were rich from stock and I need to lean them out.
