Cam and superchargered.

Finally , I got my car dynoed, but have some weird situation.

After Wot, while the acc padel was off, the throttle kept opening as you can see the graph.

Still real padel...

at the 4-5 gear changing, the spark timing is pulled too much.

Is it due to the rev. limit? the highest peak of RPM before the point, it is just 6590 RPM as I set the cutoff at around...

I got the new one, but nothing changed.

For checking , I put sensors on each bank. 15.0 afr on bank 1 and 12.5 on bank2

I checked every hardware, but couldn't solve it.

Idle is jumpy and bank1,2 ltfts are weird.

I tried to exchanged the injectors, spark plugs, wires ,coils and o2 sensors on bank1 and 2, but the...

Ah, the motor tested was not mine. One of my friends got his forged engine with stock cam tuned, at that time , I ran a little variation of cam retard.

The next time , will be tested with mine...

I just played with stock cam which has quite low profile at this time. So no limiter or lockouts for it.

I tested it on dyno yesterday with gen5 lt1 stock cam on/off, but the result was...

1. stock retard. (10* retard at 6500 rpm)

Boost level : 0.91 bar (about 13 psi)
Cylinder air mess at 6500rpm...

Sorry to pull back this thread again,

When I use the C7 Z06 spread sheet with 6500 rpm, 20Mpa , 18 Spark Advance and 6ms IPW, it tells SOI would be 261.6*. In my calculation, if I start to spray...

Thank you! Now, it is clear.

Hello,

I have Camaro 2017 SS with PD blower and it has a forged engine with TSP VVT-1 Cam. TSP gave me a sheet for cam retard, not much , but about 4* retard at high rev.

My question is that I...

Hello,

I sent my TCU to Hptuner in order to unlock it and flash it, btw my friend is using "Trifecta" and it doesn't need to unlock it and is able to flash it. I believe Hptuner can do the same...

Thanks!! I will try.

Hello,
I got my Camaro 2016 ss supercharged and expect around 750rwhp.
The problem is TCC slip. Especially from 5th to 6th gear change.
As you can see the pic attached, there is 70 rpm of TCC...

Thank you again,

Do you mean "Closed Loop Mode vs. Airflow"?

Ok. I will try mod SOI.

Thank you, Higgs

1. In my opinion, even if I do proper tune for MAF and VE, AFR shows lean condition due to the "bypass" intake air during the overlap , the O2 sensor will detect it and let ECU -...

Hello

I have installed a mild cam on my Camaro ss 2017 and my AFR gauge shows lean around 15.5 at idle and the low rev.
I understand it is due to the overlap of cam.

1. Someone advised If...

I just installed a new cam on my camaro 2016 ss Whipple S/C.
It is my first time to install a cam. The cam is not that aggressive.

Here is my tune file and log. I am wondering the rpm variation...

I posted about negative idle timing before and tried to solve it.... read all thread here , but couldn't find any yet.


I got a trouble with my stock throttle body, which shows negative spark...

Here are my logs.

The setting is the exactly the same, but the first one has minus spark timing while another one has 15~18* positive timing at the idle.

Thank you,

How can I adjust the torque model at idle? By changing the Max torque timing vs. RPM vs. Cyl air table?

Hello,

As the weather is colder, I noticed the rough sound from exhaust , then I checked the spark timing showing -3~-2* degree.
On the log of a day before the above, it showed 14~16* degree....

Thank you for the advises.

Then, the more timing before knocking, the more power anyway?
