This! My symptoms exactly, i thought maybe I was just trying to spool my turbo too fast or because it spooled so fast that maybe fuel wasn't coming on fast enough or something.

 

yeh because on the dyno you get different spool characteristics.

so you really need to check the tune on the street afterwards...

it *could* be phantom knock (from the built motor) but see what you can do with AFR/timing before using the knock multipliers to fix it

 

We have logged it several times on the street and whenever I do it doesn't seem to knock on the light or in logs.

Mine doesn't happen all the time, it just seems like when I floor it from a higher rev, like 4k or up to where i hope to get instant spool.

On my normal dyno, dyno dynamics, there was no knock but when I logged it on a dynojet there seemed to be a few 1-2 counts on spool up until 3300-3400rpm then it was 0's all the way. Not sure what the deal is I am just paranoid after blowing one motor, don't want a repeat just yet.

Regardless seems offtopic for this thread, if it is I will stop, lol.

 

This sounds like an enrichment issue. Does the X have a table that adjusts how much fuel the ECU adds when you smash the throttle? Just like how carbs have the little squirters when you pump the gas.

 

Not sure, I think the ECU just uses the MAP sensor in that situation...

You should be able to see IPW jump - if your logging quick enough

 

Does the knock on an EvoX decay like it does on 8's and 9's? I did another tuning session today on my buddy's X, and each time it encountered knock, it would just blip the number for one sample and disappear--no decay at all. Is this normal for a X?

 

it does both.

i havn't worked out why/when it will do the big ping with no decay...

 

Has anyone found a good fix for this? I'm having the same problem with the Beta version of ECUFlash.

To make matters worse, when I uninstall the beta and install the regular version (which opens the TephraMod ROM just fine), it no longer recognizes my Tactrix connection. So one version (beta) can read/write the ecu, but can't handle TephraMods ROMs, and the other version (release) can open the TephraMOD rom, but cant read/write to the ecu.

I've tried backing up the XML folders from the release version and replacing the beta XML folder with it, and it still crashes

Any help?

edit: i got it working by using beta 2990 that i found on an archive site

 

its a definition problem.

more specifically a scaling issue - ie my XML depends on a scaling that isn't defined - thus ECUFlash crashes..

ill update my XML's shortly

 

You can always install both of them to separate directories.

I guess I've been a lazy tuner lately since I meant to look for the reason. My UEGO standalone logging is finally fixed though, so time to tear up some winter tires . Thanks Tephra!

FYI I notice this happened on an '03 Tephramod v7 also.

 

Patiently waiting for ROM's for 2010 models! I need Valet mode like i had on my IX. Valet came back with my car recently with a big smile on his face as he handed me my keys....

 

Hi Tephra,

I think in 94170715 it is this item where there actually *isn't* a scaling:

I don't have that in my Tephra X v1, and it seems to work fine right now.

 

im just booting up a VM to load the latest beta - hold on two secs

 

yeh it's missing scalings:

I will update my zips

 

which I had already put into post #2..

grrr
