What injectors are you running? Might wanna add more fuel between 41-49 and 32-37. What turbo are you on? It sure isn't sucking a lot of hz compared to other cars. How much boost was on that log?

 

I have 700cc injectors, Greddy 20G turbo kit with wastegate, boost is 1,3-1,5 (19-22)

 

ok..definately wanna add fuel in 4250-5250. Also watch out on the top end.

 

Add fuel to what level? Why to add?
What about timing? What is your idea?

 

First, have you already configured the UTEC for the injectors?

Are you running open loop fueling?

Do you have a stock MAF or MAF pipe, and what about the airbox?

Those numbers are pretty low and your running fairly lean, but the MAF reading being low, is likely the reason. If your using an aftermarket MAF like a MAFt setup or Blowthrough, you may have to adjust it a bit..


From just that graph, you need to add enough fuel in your curve so you never go leaner than 11.4 AFR's at RPM's over 3200 (you can go leaner on better quality gas, but general guidelines for pump gas)

Your ECU appears to want to add more timing than your UTEC timing map, you can add more timing once you get your fuel curve set, then slowly (.5 a degree at a time) add timing and do some test runs. If you get any knock, remove a little timing in the range you get the knock, sometimes you can add a little fuel instead, but it'll be trial and error..

Rule of thumb is you want to try to maintain an AFR of 11.0 to 11.4 any richer and you'll just be wasting gas, any leaner and you run the risk of really high EGT's or knock if gas quality varies from the tank you have in the car.

Timing is subjective, since the 20G turbo doesn't appear to be moving alot more air than a stock turbo at similar boost levels, you can probably get a few more degrees of timing in your map, the peak boost level is where you have to be careful, you have to watch AFR's and not get too aggressive with timing but add a little at a time, that is where you'll build your peak torque, from there on, you want to try to maintain that torque without it falling off as much at higher RPM (Thats how you build horsepower)

 

Thank you for the detailed answer!

I have an original MAF senson, and have a greddy air filter, and airbox removed, that cood cheat MAF. I have checked my other logs and the highest MAF I had was 1600-1700. I had bigger MAF reading at the start of my tuning with UTEC:

7293 +27.2 1655 81 90 00 +17.6 90.9 +17.6 +0.0 75.00 1592 10.81

Should I ajust MAF with UTEC or just try to add more fuel. What is the MAF of stock turbo?

You mean I should not have more then 11,4 on rpm more then 3200 even on 10 load?

I have EURO 98 petrolium, maybe you know the difference between yours.

 

Under low load, you obviously can let it run a little leaner, also you can run leaner as you approach peak boost..

To be honest, a 1600hz MAF reading isn't abnormal for a car with an aftermarket intake or air filter with a stock turbo. (your correct, it cheats the MAF a little)

those last two snippets you have shown are actually not a bad "run" for an AFR, its a little richer than I run, but its along the lines of what you'd see most tuners would run.

since you say your running 98RON, you have roughly the equivalant to 95 octane gas in the USA (probably even better quality than that) so you can experiment slightly, only the quality of gas varies GREATLY in europe/asia/middle east, so you don't wan't to run a too aggressive tune and then get a tank of ****.

at 3200rpm, you have to look at what your boost levels are, but if your just about at peak boost, then your target AFR should be around 11.5-11.0 (Depending on the timing you end up running)

If you don't have an EGT gauge, you might want to use one to assist you in tuning, since too much fuel or too litle fuel can cause high EGT's, and too much/too little timing can also affect your EGT's, you want to keep your EGT's fairly low, if they climb too high, the high temps alone can be enough to melt the combustion chamber, pistons, or damage the plugs. Its just a nice way to assist you in tuning. But as long as you take small steps in adding timing, and don't run way too rich, or way too lean, then you should be fine.

If something doesn't feel right on a run, don't try to pull through it, just let off the gas look at your logs, and adjust at that point. Its silly to risk damage on tuning runs.

 

Dear Jack!
Thank for assistance!
This was a third gear run from low RPM, so the boost was low.
Should I keep my AF then under 5000?
The other problem. I really have - I could have even 900C at peak.
What are your recomendations?
Thanks
Eugene

 

Guys!
Please post your comments it is really usefull.
I have rased my boost to stable 22psi and reduced the timing. Here is what I got.

On my opinion the logs are OK. But my problem is EGT. I am very hot on 4th gear run I could be even 950C. What to do???
Everybody please post your highest EGT, and at what boost and conditions it was!
Thank you.
