So I have A LQ9 that I have added LS6 intake/Ported TB, new cam and the engine runs lean so I have to calibrate the VE-table.
I have done this before so thats fine but I am worry about pushing the...

Hi, I am almost ready to tune my engine after cam/intake/TB/Injector change. As I understund I have to replace the IFR table B4001. I have the FAST 36 (Bosch 0 288 155 868) and I found a "script" for...

I have tested both the yellow as well as the red button but it is the same. If I click on the yellow button I should see the data even if it is in paus, right ?

When I hook up my V2 to the PCM and computer for scanning I can not recive data. When I click on the connect button every thing is alright. If I then push the logg or the record button EFI goes in...

So now the scan works again (thanks Joecar). I have made a logg file just to show what I mean with slow respons.
When I release the pedal the rpm slowly goes back to idel but I cant figure out why,...

Hi Joecar,
I had flash the right BB and FW but not the config. I have done that now, will check tomorrow if it works. Thanks for your support.

Hi Joecar,

The info that you sent me about electronic throttle was about open/close parameters but i think that my throttle close direct, nevertheless the rpm goes down to 1200 and after a few...

So I have a new computer, installed latest version of V7.5 scan + Tune.
I can read the PCM vid Tune but I can not logg with Scan.
It is possible to connect to the PCM i Scan but when I start to...

I dont know if this is possible but here is my question. On a carburated engine the engine respons direct on how I move the pedal. On my LQ9 with DBW the respons is not as direct as I would like it...

Thanks all, I will have my eye on the WB lambda.

With a bottle of STP injection cleaning and 200 km of driving it is back to normal AFR (14-15), Placebo effect ?

So here is the tune.

I have observed that the AFR on my car has changed the last days. Earlier that the WB show a AFR of 13-15 under normal load. Now the AFR value is 17-18 (max). What could cause this? Clogged injectors...

Thanks for the input, I will sure give it a try. Right now we have 10 inche of snow i Stockholm so I have to wait 4-5 weeks before I can test it on the road.

I consider to change fuel from petrol to E85 on my Firebird -68 with LQ9 engine(LS1 intake).
What should I pay attention to when I change to E85?
First of all are there any parts in the fuel system...

Ok, thank you Shawn.
I have a last question. In the VET tutorial, under "additional Considerations" it is suggested that B0120, B3308, B3313 and B4105 should be changed. After the calibration should...

Nice !
How about B1301, the EGR. should I make it disable or keep it enable. :confused:

Ok, now I have made a run and collected data. It was not that easy to drive correct. When I applied the filter (loose type) there was several cells that become empty. I have hand smooth and computer...

Thank you Shawn, I used a printout of the Calc.Vet tuning guide instead of the new VET tutorial. Now I understand what to do.

Hi Shawn,

I used the "old" Calc.VE" method, I have attached the calc_Pids.txt(backup) that I used.
I looked into the new Calc VET-method instruction and there is something I do not understand....

I would like som help with tuning my engine. So, I running a LQ9 in my Firebird -68. The engine is stock inside but the intake is replaced with a LS1 and I running long tube headers with deleted...

Yes Joecar. I have my LC-1 permanent attached to my car and it work fine just 4 month ago.

I know there are a lot of threads about connecting LC-1 to V2 but that has not helped me. I have FS V2 with the LC1 connected via the serial output. When I parked the car for the winter it worked...

Hi, I have 2002 LQ9 (6.0L) in my Firebird -68. When I rew my engine the rpm drops fast from lets say 4000 down to 1500 but then there is a delay of 3-5 sek from 1500 to idle (600 rpm). This is little...

Do you mean the B5001? If so I have already adjusted that.
