i have 2 questions for you all i hope i did not leave something out. all so no codes that the SC can read.

1.I have a SC 1705 programmer hope to get a PHP soon, but if i get on it hard the trans well slam in to all of the gears when shifting it dose it more in the high HP mode, is this good or bad. when i changes it well rack the hole truck and very load.

2. i can make my turbo surge when just taking of slightly fast and when i push it some at highway speed, should it surge that easy?

see sig for modes.
Thanks

 

Do you have a shift kit or any other modifications done to the trans? The SC will raise line pressure but should just be firm
A slam shift is not real good

 

no trans kit but it slams in very hard, more in the high hp mode.

 

How does it run in stock? SC seems to have problems with trans. shifting. Do you have gauges and upgraded exhaust?

 

no gauges i need some, it dose not seem to do it in stock mode. i think it is the sc. is that normal?

 

Has it always done it with the SC or did it just start

Can you program the SC like you have a shift kit and use stock trans tuning .That would lower the line pressure.I don't have any experience with the SC but the hypertec you can

There was a post about EBP sensor making the trans shift goofy and also brake light bulbs

 

Ray makes a good point about the ebp sensor. Try unplugging it and see if it makes a difference.

 

When I had my SC 1705 I just got clean firm shifts, not like a modified VB firm but firm versus stock. Not to alarm yaa but you might want to keep an eye on that. Any blinking going on, on the shifter, OD button???

 

no od blinking and you cannot select trans kit. i can try the ebp but it only dose it with the SC on it not on stock. i think it is just the cheap Sc that is the problem i only paid $50 for it, i need to get me a PHP.

 

No, I mean't the shifter ****, the OD select, on or off. Not much more to add but custom tunes you can't go wrong. I still got my SC for code reading, for fity bucks keep that. It's no AE but its worth its weight in gold to read codes..I think PHP is running a sale right now, you might want to check out their web-site..DP just came out with a new chip, F-8 I believe, check theirs out too.

 

i well check it out, i have run it in stock and it well not do it so the sc is the problem, i well just stay off the pedal. as fare as the trans having problems i hope not and it dose not give me any trouble, works great when driving normally.

 

my 1705 doesnt do that, i cant even tell that it shifts any different really. my ebpv was rusty and the tube was broke in two different areas, changed it and no effects on anything there
