Re: Tune for bracket racing consistency

1.0 is where the car makes the most power and runs the most consistent laps down the ttrack.

Re: Tune for bracket racing consistency

What lambda should I command for the E85? I run OL all the time. I run it at 1.0 on C110 race gas.

Re: Tune for bracket racing consistency

Any harm done if I just drain gas, flush, and fill with E85 and adjust the tune? Stock 19# injectors with 255lph pump. Will everything handle it?

Re: Tune for bracket racing consistency

Here's an odd question......with it being colder outside, is there a way I can hook up a switch, or use what used to be the a/c wiring to be able to switch on and bring the idle up to say 1700 or so in the staging lanes if I need to put a little more heat in the engine quicker? Kinda like using a le...

Re: Tune for bracket racing consistency

Re: Tune for bracket racing consistency

Everything is working great. Car picked up .8 quarter mile. Slight issue, when I deck it on the starting line there's what I can only describe as a delay almost like a lean bog. But it does it even when not under load. Just a normal rev. What does the tune need to make the throttle response instant?...

Re: Tune for bracket racing consistency

So my c4 swap went great, the t4m2 tune works wonderful with no stalling going in gear or anything. One question is what table do I need to start in to shorten the hangtime that happens at about 1400 rpms after a rev or a run? It comes down very nice till 1400 then hangs for about a 5 count before g...

Re: Tune for bracket racing consistency

I realize how the c4 transmission works, I am taking out my AODE transmission. Can I still run the tune that I have? Or do I need to change over to the T4M2 tune?

Re: Tune for bracket racing consistency

I got that all sorted out. Much better now. Car repeats very consistently. I am putting in my good C4 and converter this weekend. Do I need to change to the T4M2 tune or will the U4P2 tune work ok still? If I need to change, is there an easy way to transfer all of my little changes over to the T4M2?

Re: Tune for bracket racing consistency

No I dont believe I am. I'm just wondering why it is commanding fuel that isn't in any block on the table. How is that possible?

Re: Tune for bracket racing consistency

Ok...so i have a lot of track time with this car now and i have tweaked about all i know to tweak. It runs consistant but slow. which is fine. but i just realized i didnt compensate for the fuel pressure change to 55 lbs by raising the hi slope. I changed it by the % of fuel pressure change and i wi...

Re: Tune for bracket racing consistency

Adjusting speed in the shift functions had no effect on my WOT shift rpms. Still occurring 1k-1500 rpm late.

I did notice on the dashboard that RVSS and VSS are off from each other by a progressive amount as speed increases. Could this be part of the issue? And how do I correct this?

Re: Tune for bracket racing consistency

When testing the car at the track last night, I have WOT shift points at 4k and it shifts into 2nd at 5500, and into 3rd at 5000. Any way to lessen the delay?

Also the 1-2 shift is very lazy and long. 2-3 is quick and firm. How can I make the 1-2 feel the same?

Re: Tune for bracket racing consistency

When you are in the edit gauges window, there's a bitmap labeled FLAGS3. I was wanting that on the dashboard so I could review logs and see what the fuel source was doing
Under different conditions but it won't let me choose it for display.

Re: Tune for bracket racing consistency

Perfect. Thank you sir. So is there a way to put fuel strategy on the dashboard? I see it in the edit gauge window but I can't seem to get it to display.

What is Des-slip on the dashboard and why is it at a constant 1020? Is that correct?

Re: Tune for bracket racing consistency

I don't suppose this could be a relay issue instead of a tuning typo could it?

Re: Tune for bracket racing consistency

Thank you for all the recommendations. It seems to be fairly happy right now.......

Went to change cooling fan on/off speed and now the fan stays on regardless of temps I enter. Any clues where to start with that?

Re: Tune for bracket racing consistency

Thank you for the suggestions.

The idle is actually opposite of that. It idles great when in gear during closed loop but when you go into park it absolutely won't idle unless tps is open to .04. Ispbm r remains at 0.0

Re: Tune for bracket racing consistency

So when setting the idle mechanically in gear, I have found that everything is great when in open loop, but when it switches to closed-loop, the car will not idle in park. It's like it stops adding idle air when it goes to closed loop. I know I shouldn't be setting idle in open loop, it's just somet...

Re: Tune for bracket racing consistency

Just double checking, the u4p2 tune shouldn't need anything extra changed for cat-less exhaust? Other than obviously tuning for fuel needs as normal?

Re: Tune for bracket racing consistency

In reading your transmission write up, you specify to divide old tire size by new tire size and multiply it by old gear divided by new gear. But in the example you show, you divided the tire sizes opposite of what you stated. Can you clarify please? I am going from 273 to 410 gear and from 25.7 to 2...

Tune for bracket racing consistency

I am wondering about using the U4P2 for bracket racing. I want the car to be as consistent as possible and predictable to weather change. I am used to carb fueled cars. What is suggested for consistency and predictability? Locked timing and open loop would be my first two guesses. Any suggestions?
