Hello guys, I have a question about the tune for my LT4 MT6.
Also, first I'm from Germany, and sorry for my bad English.
I want a tune for my car but in Germany we have maybe 3-5 Ppl they are can tune the car but want utopian prices or don't have time.


MY mod list :
Kong snout and x ported stock supercharger with 2,30 pulley
Kooks 1 7/8 headers with 200 cpsi HJS cats
rotofab intake
103 mm Nick williams thorttle body
mighty mouse catch can mild version
NGK 6trix sprak plugs
MSD spark wiring
no crush kit rear exhaust side
it's running here in Germany with 102 octane fuel
also like 95-97 octane in the USA
93 in the usa like here 98 octane

I have already installed AEM wideband sensor directly after headers
and I have already installed all 4 o2 sensors before and after cats i hear lt4 need secondary o2 sensor it's better for the tune !? That's telling me the tuner on the phone here
so, I need a good tuner for my car also what I have is hp tuners with mpvi2 controller I unlocked already my ECM on hp tuners.
And make a little log and I see the throttle body opening just 60% (2000-5000rpm)
I am still unsure whether I should have remote tuning or log per in the USA done by a good tuner or here on the Dyno in Germany, myself can only log and possibly change a few small things, but I don't do that because I have no idea from tune have
That's why I'm asking you for advice on what I should do. In Germany, dates for tuning are only available from January to February

thank you for supporting me

While I am not advocating and moderator please delete if not allowed. My recommendation based on your location and the hardware you already have is to check out Evans Performance Academy. There are many many video's that can get you knowing what to look for in logs and making the right adjustments. Its a monthly subscription of around $50 buck a month and once you feel comfortable of course cancel your subscription. Sharing this information based on my own path of learning the tuning path to learn what does what and what tables impact drivability.

I would look into a remote tune, Jannetty does a lot remotely. He’s a really nice guy and don’t know if anyone who’s had a bad experience with him.

I would second DrBlockHed on this one. Hit up Ted Jannetty and he will work wonders remote tuning your car for you. It looks like you've already got everything needed to get started so hit him up. Here's the link...

Hello guys sounds good thanks for the support ��

I hear a lot good things about the janettyracing.

Hp tuners academy is very good but I think I need few months to tune it self and I don't want be any experiment on my car.

Maybe in next time I will do learn more about the hp tuners to tune my cars maybe the basics ��

+1 for Jannetty - You have everything needed for him to get you right. You'll get more interaction if you plan to do the work on EST timezone. Also, not sure what the weather is there this time of the year but this may be a limiting factor in remote tuning as you have to do full throttle pulls at some point.

When he is done, you'll neeed all the traction you can muster when your car goes on boost!

hi guys we are now on tuning the car it runs pretty well but i see one small problem corrected me if im worng i make a screenshot but it looks like @wot on high rpm throttle body was close beforre i hit the revlimiter my tuner tell me its like normal but i dont think that so can anybody tellme what we need to make to corrected this part ?


Also on stock tune i logged with same mods the tb closed direclty on the revlimiter without close
if i zoom it i see the tb close on the stock tune too but its not so long like with my tune maybe tune issues !?



first tune picture after tune ( not finished yet )



last picture on stock tune tps like more open on higher rpm
maybe charts or layout issues ?






stock tune log

tune not finished we are working on it but it runs really great

Also you are sure it hangs with the torque management?? Also I'm right with that it's not right so !?

It doesn't look like TM is pulling your timing down (at least where the cursor is).

But - if I recall (and someone correct me if so), but I wonder if you hit the rev-limiter, as was already stated. I believe there is a MPH and an RPM limiter, and the primary control is by vehicle speed (MPH/KPH). In the scenario I'm thinking about = if you pass the MPH/KPH limiter before the RPM, the throttle might close. I think if you hit that limiter fast/hard enough, you could trigger a SPARK limiter, too. My point for this, is if you changed the REV limiter, you have to correctly balance the MPH/KPH limiter, too.

On the other hand - if you haven't touched either yet, it could easily be the ECM choosing the either close the throttle or actually pull SPARK ADVANCE (which I can't tell from this screenshot). I have found in the few times this has happened to me (and it's documented elsewhere, too) that the throttle is for slower, and less aggressive torque reduction, and the SPARK ADVANCE (it would be RETARD in this case) is when it needs to be an immediate control over the engine speed. In this scenario - you should be capturing TORQUE CHANNELS (you may be, but you don't show the lower half of your CHANNEL list), and you could see if it were IMMEDIATE or PREDICTIVE that could be intervening.

I would consider, either adding another CHART with the TORQUE values, or creating a completely new CHART altogether, with ONLY the TORQUE values, so you can see them easier. You tuner could likely be correct in that it's normal, but adding these channels could likely prove it either way.

thanks for your response



i make a screenshot again for me is that not normal if anybody want to watch in my tune file they can do this every time

Also guys i found the problem between the shifting boost loses it was the bypass valve it was the grub screw it was to lose. no its working fine car runs now 5.2 sec 100-200 kph just on only pump gas 97 octane
