Looking at your stock timing, its real aggressive compared to the UTEC's timing map.. Did you mention to me you had a reflashed ECU? (I don't recall)

I don't think I've ever seen 24 degrees before on a stock ECU (22 or 23 is the highest I had seen, but it could be the nature of you removing 19% fuel to compensate for the 660's)

I'll do a quick plot and see what it looks like..

 

My ECU is not reflahsed, only using the UTEC.

Thanks man let me know

 

Ok.. according to data log lab, its about 289whp and 265wtq... you can pick up some torque with a little more aggressive timing +1 or +2 degrees over 3000rpm.. assuming you don't get any knock.. but your numbers are on par with what I would get on my car.. FWIW I think data log lab reads a little high..

 

I think its lower, I got 320whp and 280wtq on a 4wd Dynojet with the same setup and 91 pump gas.

What do you think?

 

Wow, if the numbers are off like that, then my car's making closer to 350whp (with similar torque to yours).. Thats scary.. However run to run consistency has always been important..

Looking at your AFR's in your dyno sheet.. you have what appears to be one thats a bit lean (close or over 12.0 AFR's) I can't tell which was the lean run, hopefully not the peak power one.

The numbers look "Right" I think I'm not factoring in enough loss in the driveline on the program.. but the curve definitely looks close to what I got..

Honestly, every dyno is a little off, and correction for weather and other things could have an affect on the readings.. However even if the numbers I get are off, they are consistent so it allows me to tune..

 

you probably can pick up a little bit of power with a little bit more timing, but with 91 octane I don't know if you'd want to try for that..

I still can't get over how "off" or low the numbers from the software are, but this does give me a little calibration data to work from..

It does say that smoothing is 0, and its SAE HP (WHP I assume) which likely means its corrected for temp and altitude..

Ya know.. It only goes to show that its difficult to compare dyno numbers on different dynos..

 

Do you know where to add timing? I will try it and try to run my car gain in 3rd gear.

I will post the log off the UTEC so you can analize it again.

By the way the car achieved 330whp and 300wtq on 91 with 1 gallon of C16

That probably equates to 92-93 Octane?

Thanks

 

From around 4000-8000 rpm.. I think you'd pick up a bit of torque by doing that.. assuming you don't get any knock (and your not running too lean) your timing at upper RPM's is 16 or so degrees, you can likely get another few degrees out of it, but its going to depend on your AFR's and the gas.. You don't want to tune on the ragged edge though.. at peak torque you can add .5 to 1 degree where the torque curve ramps up.. do it .5 degree at a time though..

 

Hi, MalibuJack

I have emailed you my 91 aggressvie map, can you do the changes to the timing?

As soon as I receive the revised timing you did, I will run the car to datalog the 3rd gear pull.

I realy appreciate it.

Thanks

 

Its probably better to do it yourself, you can download a copy of UCC2 and edit it..

The only reason I suggest doing it yourself is so you can get some understanding of what it takes to do it. Plus I didn't realize this was a tuner map and don't want to Step on anyones toes.

This is going to be trial and error though, without a dyno and good det cans (audible knock tool) you probably don't want to arbitrarily change the settings.

 

Hi, MalibuJack

Here is my latest run tonight, I revised some of the timing up top like you said, no knock what so ever on the run.

Please save the attachment and please review it.

Thanks

 

Ok.. you gained a few HP from what I can tell (different weather could account for this) Torque didn't improve much since you didn't alter your low RPM timing.. however your torque curve is now alot flatter (I'm sure you probably felt that)

I could be wrong, because I don't remember which calibration file I used I'll have to check this again later.. but it looks like you picked up around 10-20whp and about 10wtq

What I do notice is the factory ECU still is indicating it wants to run more timing in some areas.. but thats likely due to the altered MAF readings...

I'll have to run this again on my other laptop that I use for tuning my car but it definitely looks like your torque curve is alot flatter than it was previously, and you didn't lose anything in horsepower..

 

Hi, did you also recevie my email containing the the revised map that I did?

What do you think about the safety issues on the run? Do you think I can run the map for daily driving?

I don't see any knock from start to redline, that is a good right? Should I turn up the boost? what do you think? I'm boosting 20psi right now via 91 pump gas.

As for the torque, I can't seem to get it up higher, what do you recommend doing to make the torque higher, I want the torqe to be less than 10 or equal to the whp I'm making. That would be a great tune for the UTEC. Im sure its also possible, but I don't know where to adjust the settings.

You are correct, about the 20whp gain and 10wtq from the last map

I was also wondering if I change my downpipe to 3inch, and maybe change my mas pipe and filter to a bigger HKS one, do you think that I would pick up the missing torque?

What you said that the torque is flat? Is that a good thing?

Thanks for helping me out on this for the umpteenth time
