Hi 04silverado6.0,
You're not late to the party :). I'll give this spark table a careful try watching knock retard closely.

Thank you!

Thank you 04silverado6.0, that would be awesome if you could do that. First of all my "hardware" set up is as follows:

GM LS1 from a Camaro 2002
GM LS6 cam
GM LS6 heads (Cast 243)
Holley...

Hi,
In my street rod I have a LS1 engine from a Camaro 2002 with LS6 cam and LS6 (243) heads. I'm also running it in SD mode without MAF sensor. I have tuned the VE table using wideband lambda and...

Thank you 2xLS1 for your reply. Very useful info. Both segments 7 and 8 are different so I guess I have to SPS program it first.

Hi,
I'm about to replace my broken E38 ECM in my 2008 Corvette C6 with LS3. The new ECM is from a 2008 Corvette Z06 with LS7.
Both has the same service no #12612384. The broken ECM has os no...

Ok, so with some subscription on tis2web and my Tech 2 device I should be able to do SPS programming it first. After that performing a "Write Entire" from my HP Tuners.

Do I update the VIN numer...

Hi!

I have tree questions regarding replacement of ECM:

Can I safely make a "Write Entire" to a new E38 with the same service no as my existing ECM, without any risk having it bricked? Both...

Sorry, was a reading/typo error. It was pin 59 (circuit 5991) I was referring to.

Hi!

I have an E38 ECM refusing to activate the ignition relay at its pin 47 connector J1 (circuit 1339) when switching IGN on. I also get CANBus errors U2105 and U0100.
Should the ECM activate...

I got information from other sources it should work despite not reading/writing those two segments.

Will I need 2 or 4 HPT credits to write my current ECM content to a new E38 hardware?

Thank...

Hi!

I'm going to replace my E38 in my 2008 Corvette C6. Is it enough with 2 credits for my existing ECM or do I need another 2 credits for the new ECM in order to maka a "Write Entire" with my...

Hi,
I have a newly rebuilt 4L65E behind a LS6 in a Ford -32 hot rod. Everything works fine but I find the shifting too hard at low throttle (easy driving). I guess lowering some pressure should be...

Thanks for all feedback!

Here is my tune file. The engine tune has been modified a lot since I've made several modifications to the engine. The engine is, in my opinion, is running fine.

The...

Thank you blindsquirrel for your reply! The idle airflow is perfectly tuned and the in-gear values are in fact the same as the P/N values. The STIT is close to zero all the time at idle and the rpm...

Hi,
I have a LS1 with 4L65E in a fairly light Ford -32 hot rod. The transmission tune is all stock from a Camaro Z28 2002. The issue I have is when I go from neutral to drive at 650 rpm idle it...

In what way can you filter besides setting "cell hits required"? Some example?
Thank you!

The origin of the tune and the VE table is LS1 (Camaro 2002). Maybe I should start with a LS6 VE table (from a Corvette Z06 2003)?

Hi,
I'm running a Ford -32 Coupe with LS1 from a Camaro 2002 with 243 heads and LS6 cam, Holley single plane manifold and Holley 4 barrel throttle body. I have run 5 iteration, each with a 20 min...

Thank you both for your input. The reason was that the idle airflow was set to high which the ECU compensated with STIT of -4.5. When I shift do drive the STIT jumps to 0 (by some reason?) which...

By some reason the rpm jumps up from 800 to 1500 when going from neutral to drive. The test I made was done with the vehicle lifted up with rear wheels spinning free in the air. It seems to me that...

Hi!

I've made a few test in a dyno and discovered it runs very rich at WOT despite low values in Power Enrich EQ Ratio table. It drops down to nearly 10 with enrich ratio around 1.25!? Log and...

Hi!

Can anyone tell me if 17 is a reasonable spark advance at 6000 rpm and 250 lb-ft on my engine?
The engine is a LS1 with 243 heads, LS6 cam, Holley Single-Plane Intake Manifold 300-163, Holley...

Reducing it by 75 HP (sorry for my bad English).

Hi!

Is there a way of reducing the power of an LS1 engine with something like 75 HP?
Is reducing the spark advance the way to go?
How much roughly should I reduce the spark advance?
Is this a...

Thank you kevin87turbot! You were so correct. Now the IAC sits around 30 when engine is warmed up and with idle rpm spot on.
