Thanks Joecar, I hope not. I will monitor it.

Hi Joecar
I havent got it onto a dyno yet. I'm trying to get as mush tuning done on the road so as to not spend to much time on the dyno. I don't suspect the box having a problem but you never know....

I have a 4l65e in a 4x4 Nissan with LS6 running 36' tires and 4.33 ratios and am busy tuning the motor (SD) My problem is that when it changes from 1st to 2nd with my foot down hard the box changes...

I have turned the VATS off, still no joy. I have loaded a 1024kb tune onto the RR and had the truck running. I dont have a 1024kb ECU to use in the vehicle but have the 512kb ECU that I ultimately...

I have had no problem running my RR with EFILive and windows 7. I did have to remove the RR driver and then use the EFILive driver and that sorted it out.

Hi Guy's
I have decided to start a new thread instead of hijacking limitedcv8r's thread.
At first I could not load a 512kb tune to my 1024kb RR which I have now sorted out by holding the Shift &...

I have managed to load a 512kb program into a 1024kb RR by holding Ctrl & Shift down when asking it to load, all is well now

Hey Ross
Loaded the files last night and all is well, can now get into systems file and change fan on/off temps.

Thanks again for your help

Dennis

It was a while ago but if memory serves me correct EFILive program was not compatable with this PCM, I think!!!
I will try again tonight and see what it dose.

Thanks NODIH, I did try to download a 512kb program a while ago and was not successful, I will try again maybe I did something wrong.
Thanks
Dennis

Thanks for your help, we realy appresiate the help. The OS is correct so will try to load it later and will keep you posted.

Thanks for the reply NODIH. Another question, how do I get a 512kb program onto my 1012kb RR? Is this possible?

Dennis

There is only one fan connected (no space for 2) and connected via a relay only on and off not 2 speed.

Thanks for your help
Dennis

The fans are controled by the ECU and come on to late. He is probably going to have to opperate them externaly to get them to come on sooner ?

Hi GMPX, thanks for your reply. The ECU is a E67 not E68. This is a GM performance ECU.
He can open the engine calibration,engine diagnostic etc. but not the systems file where the security, fan...

Hi, Im' posting for a friend who just fitted an LS2 with E68 ECU into a Wrangler. He just got V2 and cannot get into the systems to adjust fan on/off temps, actualy unable to get into systems at...

Hi Guy's, I'm realy new at this so forgive me if this is a stupid question! Can I connect my RR to a laptop and connect my scan tool to the same laptop at the same time to monitor or log while tuning...

I fitted the ECU last night and started the motor, she started easily but idles very rough. I can rev it and it starts to clear up for about 30 seconds then cuts out. If I start and let it idle it...

I will need an OS from a truck so as to have the 4x4 low tune in the trans.

Thanks, I will try running the engine tonight and let you know.
Are any of the tunes you have for 5.7l I cant seem to find any, only 4.8's and 6.0l. I know that 5.7s wernt offered in trucks.

Hi slows10
I have downloaded another tune and loaded it onto my ECU and it seems to have taken. I think it is because I was trying to make changes before loading onto the ECU, This time I loaded it...

Hey Taz
I have tried to load 3 tunes from tune file but I keep getting a message saying that EFIlive dose not support this ECU...? I have been able to downioad the tune and do some changes (speedo...

Hi Guy's
I have been troling this site for a few months now trying to get my head around EFI tuning. I'm very new to this electronic tuning, more mechanical orientated.
Here is what I have and what...

I have checked my RR ECU and it dose have the IAC controll in it so it should be OK for my application??? What vehicle would use a 1024 k ECU that runs DBC??
