Mazda6 help

[03JDM6]

Does anyone have a base map for a 03 Mazda6? please help!

Highly dout it.  No one with a mazda 6 is running the fic.  Maybe 1 or 2 people if that. For one it can't do timing advance.

Do you have an I4 or V6?

Boosted or NA?

You can make a rough base map using the software.
Right click the fuel maps and create base map. It will ask max boost and injectors sizes before/after.

I have a I4 and its boosted. I got the vacuum part tune pretty good, just for some reason when I try to go into boost it gets really lean. I'm running on stock injectors do you think thats what holding me back? Thanks for the replies.

What turbo are u running?  Is it the F2 kit? And how much boost u using?

First is, just shooting in wind since I don't know the above questions I put...

1. Stock injectors on the 2.3L. Are only good for about 4-5psi...and they are getting close to about 80% duty cycle at that level which is borderline unsafe

2.  U never boost a car with stock injectors. Especially if you plan on using it for a daily.

Once you tell me what I asked above I can help u more.  But if you are running like 8psi....you are going to have two problems..

1. Injectors running out since they are stock
2. The maf pegging if you haveent clamped it.

- if you haven't clamped the MAF yet, clamp it at about 4.0volts

I would recommend you a minimum of 30lbs/hr injectors...better tho would be 36lbs/hr set.   Being as u are running the stock injectors...I highly doubt you built the motor so I would not run over 8psi on it. Therefore 30's or 36's for injectors will be fine.

IIRC your injectors are EV6 style....if u can snap a pick of your injector and plug and post up I can tell u want you need.

I am running a custom turbo. Its a 16g from a vr4. From what I've heard the wastegate opens at 10psi. I know thats a lot for stock internals and for the motor but I can't seem to find a 7 or 8psi wastegate anywhere. Right now I believe I still have to clamp the MAF and been looking at RC injectors. I e-mailed them and they say I could use injector part # SL4-440 and all I have to do is change the connector. I live in Minnesota and there's not much tuner shops that i know of besides MAP performance. I am planning to get it tune this spring. Heres some pic of my car.









I will post pic of my stock injector when i get a chance. Thanks for the infos punisher!

Ok, not trying to sound like a dick, but are you trying to pop that motor?   Anyway, 10psi is too much for a untuned motor with stock injectors.  Have u even dialed back the timing at all? If so how much?

As for the injectors, yea u can use those, but why when u can get something that's a direct replacement.  IIRC u need a set of siemans deka mototron ev6 30 ot 36lbs/hr injectors.

If you ain't building the block u donnt need any bigger than that because the motor won't support the boost you need to run to utilize those.  Get me a pic on your injector when u can.

You need to stop boosting your car now until you get the injectors and clamp the maf properly.  4v to start with the clamp and see how it does, but do not boost anymore until u have the proper injectors and timing retarded at least 15degrees to start since u can't run less than the 10psi spring.  Rule of thumb is for every pound of boost pressure take away 1.5degrees of timing off top. Then dial it back until you are making no more incrrease in power or ping starts increasing or worse becomes audible. Then retard 2 degrees and you should be good. But that was a rule of thumb not an absolute.

Thats ok, I really need to learn these things . I will look for those injectors. Do you know where I can get them? here's a sample pick of what my stock injector looks like

.

I know that its dangerous boosting on stock so I haven't been playing with it for a while until I get things right. Another thing I was going to ask you, how would i clamp the MAF? do i just input 4v on the whole chart? I know there's a video on it but i don't quite know it. On the timing i can do that. Sorry for asking too much questions but you're a lot of help to me.
