Hi guys, I just did a 3rd gear pull yesterday and am wondering what you think. Looks like theres some knock especially around the upper rpms. I'm not sure what I can attribute that to. Help?

I just researched in some other threads and found out if the road is bumpy that can show knock on EvoScan? Is this true? I know the road we were testing on wasn't smooth...


Also, what programs do you guys use to map out your logs? It's hard to really see whats going on when you just hit playback on EvoScan.


Any help would be appreciated. This was a jestr e-flash. I only have a MBC so far, and he advised me to up the boost to 22psi MAX.

Later,
Brent

 

EvoScan v0.98 will have nice log viewer, so you can scroll and zoom your logs.

 

Thanks for the info. Can anyone take a look at my log?

Any Advice?

 

If you did a Jestr M1 flash, you are suppose to load the map, do some datalogs, then offer john the opportunity to fix your flash according to your logs if knocks occur....don't just go on here saying that this is what happened when you put his flash on the car...

I highly doubt that a bad road is going to pickup on the knock sensor...

I just got my car flash by Jestr tuning myself, had the high knock counts, sent the logs back to john and bam....knocks are virtually gone...Take a look...

 

You sound defensive...

I understand this totally, but thanks. I've sent logs to him, with no reply. Thus, I'm posting on here.

I'm not speaking negatively in ANY means about him. He's answered most of my questions very quickly. I'm just trying to get advice as to what may be the culprit, or if i need a reflash.

Is it possible the Air Temp changes here during the winter can affect it much as well?

 

I have seen vendor bashing on here too many times dude....this guy does good work....but come on...its the weekend, give him a chance...lol....

 

First off, you need to log just more than 1 gear. 2-4th gear pulls are goood. diff gears give diff readings.

There is normal knock level there.
You are not pulling timing.

Knock counts between 0-8ish are normal.

If you knock and pull timing then consider a revisement.


But relog all ur gears and try to get a wideband.
On tht base flash i recommend going back a notch to max 21psi on stock Fuel pump

 

From what i have heard, anything over 5 knock counts and the ECU goes in to the low octane maps...

 

Lol no^

 

I'm not sure I would call up to 8 counts 'normal'. The ecu seems to pull 1 degree at 2 counts, and 3 degrees at 8 counts from what I've experienced.

 

im not sure who told you 0-8 counts is normal... but i'll help out, they lied to you.... or told you that so you would stop bugging them or something. You should tune for no knock, even a slight count here or there is acceptable, but not a continuous anything, and damn sure not 8 counts. thats not phantom knock at that point. With the map i am using, i have no counts what so ever... i may encounter a count or two in 4th gear, but none in 3rd.

i dont think he was vendor bashing either, he asked for someone to read his logs and let him know what he needs to do... IMO, i'd say email the tuner again and let him know what you need if he doesnt get back to you by today, im sure he will fix it as most vendors do. If he doesnt, the only thing you can do is check your air fuel for the knock range... if you are running an air fuel you are happy with, then you will have to pull timing in order to get the counts down

 

yeah agreed... 1 - 3 knocks here and there may be ok but any knock number of any consistent range is bad

 

None the less an M1 flash from jester is a base flash for pre determined conditions. If he wants to solvethe problem he needs to get a full tune.

 

Hi

You could try pulling the timing back a couple of degrees where you are getting knock. What you realy need is the AFR, this would be most important to check.

where are you getting the wb02 numbers from?
