Log check on E30. Map 3 feels stronger than Map 4...

[DavidinGA]

'21 GT2 awd
Intake, plugs, JB4, stock otherwise.

First time running E30 mix and my first time trying anything beyond map 2.

I filled up with 4.5gals of E85 and the rest with the same 93 I've been running.

1st impression with map 3 was damn that's much stronger than map 2. Then I moved on to map 4 a few days later and it was like meh were did all my power go...? I ran map 4 for a while and then went back to map 3 and all my power came back.

Is my E mix not up to par for map 4 or what's the story?

I'm still learning how to read the logs; could someone give me feedback on them?

Should I try Map 5 for kicks?

Thanks!

I checked them and while Im not the best at reading logs it seems fine to me. You do have a lot of corrections but they are all small and 2.3 or below which is good. The main rule Im following when reading your logs (from what I've been told when running E) is

Trims not above 50
FP not above 11
ign2-6 not 3 or above

With my not so expert opinion following this rule things look good.

For me personally, I don't think I can really tell the difference between map3 and 4. I can switch between them but I really feel like its the same thing, maybe I'm just too used to it idk. The biggest jump for me was map 2-3.

Ok, thanks.

Have you yourself tried map 5?

I actually haven't but I didn't know what was required for it. I assumed it was cpi and I never touched it lol. I might actually because my logs are just all 0s on map3/4 so It wouldnt hurt (perhaps) to do a pull or check it out.

Ya I don't understand it either, but I know a guy running map 6 on E30 too.

I know map6 is user adjustable so he probably made some changes that were recommended to him or something like that

Simply because your map3 actually runs more boost than your map4 in those two pulls. That just how JB4 works, the “Target” doesn’t mean the extra boost adds on stock boost pressure. Once you start playing with map6 you’ll start to feel our struggles lol.

I don't have the logs open currently but why does it work that way? Does map4 try to keep boost similar through the power band therefore it may hold a lower level of boost? While map3 puts out the highest number it can?

That’s just simply how JB4 works as a piggyback, lying to ECU about the boost you’re running so you are running more. So the ECU_PSI is the value that ECU sees instead of your real life map0 boost. Map3’s target is 6psi tapers to 5psi and map4 is 7 tapers to 6, that’s only 1psi difference here so the actual boost might be same or lower. Once you try to dial the car with map6 you might find it’s funny that adding big numbers (7-10) wouldn’t give you better result than playing with (3-6) most of the time. It’s really frustrating at first.

Do most people go to map 6 over Maps 4 and 5 then?

Any links to threads suggesting how to setup map 6 optimally?

Thanks

What is your current map? Assuming you’re able to run map2. Which is 5psi taper to 4 for target. Then you should start with flat 4psi then try to add slightly more timing on 4500 5500 and 6000. Also keep your eyes on boost spike after shift, if that bugs you too much then you can just stay with a flat number for all rpms. Some cars just hates map6 without EWG wire or adjust EWG with backend flash.

I'm on map 3 or 4 now. I don't have ewg wires.

Make sure your log is clean and safe first then you can do something like this:

Then try start with flat 5. And add slightly more to 5000(like 5.5) and a lot more to 5500(like 6-6.5). This will make the boost flatter then you can do fine adjustments accordingly. Extra boost(like 5.5-6) for 6000 rpm really depends, some car/some BEF settings just hate you to adjust boost right before shift. EWG will help but get it dialed properly with BEF is ultimate answer.

It’s just a rough idea of how we dial the map6. Anyone who failed to analyze the log and simply copy other’s map6 can definitely lead to catastrophic failure.

Here is a run on Map 5. Map 5 seems slightly stronger than Map 3.

Look good?

Your trims went above 50 on WOT. I know this isn't ideal but I also don't know "how" bad it is since you only went over by a few numbers. I'm sure Yves will clear it up but the rest look fine to me.

From what I gather might this mean that my e30 mix is actually a little higher than 30?

Also, if I had made this run in the winter I would probably be running lean, right?

Your peak and continuous boost here is obviously higher than map3. Trims are about there so there’s no extra room for any more boost and E.
