New To dsp - SRT Forums

Chief · 11-01-2009, 01:03 AM

So got my build done, and went ahead and started messin with dsp. I have my neo still installed but set to zero. only low throttle adjustments are being made to keep the idle smooth. 750 injectors

Seems to be running nicley only 15-16 psi but it sucks you can only take up to 10 degrees out. Im runngin 8:5cr and at 6k 20-21 degrees i get 5-6kr. EVERY time. But i heard MANY get this kr around 55-6k?

Also i wanted to get my 3 bars put on and have it rescale from nigel, and try to street tune it. is there a way to get my timming backed off a little more so i can play more with it between 15-25 instead of 20-30? I heard nigels rescale are pretty nice, he can also lower the sensitivity on the knock sensor a bit. I have it torqued down 195inlbs, but still RELIGIOUSLY get this knock at 57-6k.

ALSO wot 3rd to 6k than let of throttle and go to 4th and wot it BOGS and falls on its face? This MAY be related to low boost issue. being im running a 65lb min turbo at 15 psi LOL i remember long time ago i could never shift into 5th after 4th and give it wot on 20 psi it would bog, yet on 25-26 she would pull right through and haul ass. but from 2-3 no hesitation at all. 4th is also QUITE a bit rich than 3rd. I got 3rd in mid 11s where 4th is very low 10s if not flat tens at times.

O and tried spraying meth to get rid of that 6kr at 6k it did NOTHING!??!?!? WTF?

You need a rescale and 3 bar sensors to start

Actually you need the 750 injectors scaled more than you need 3bars, then once your fuel is back in line get the 3bar sensors.

The Neo/injectors are causing the Bog, eratic A/F and jacked up timing,,,,98% of your issues.

Of course you can do both at once, but you need thise injectors scaled and that pos Neo in the trash.

lol yeaa. im gonna get my rescale from nigel as soon as he gets back on the forums. and install the 3 bars. and disconnect my neo. Hopefully i can get it running right.

Well might as well get them both rescaled at the same time so you don't have to pay an extra $50

Agreed

Nigel knows what he is donig, and you will get a tune with the proper timing and fuel table.

If you want (I know you problably won't) I will get the rescale and timing table adjustment done for you today if need be, for free. Call this "me trying to make things right" with you. Let me know and I will make sure you have something to run on before the close of business today.

Thanks.

I appreciate it, but I already sent nigel the money and my stock tune... i heard his rescale are pretty damn good, and alot have been able to street tune there cars with out ANY issues. He said he would have me the rescale by the end of the day

I really need this TPS connector, could that ALSO be affecting my wot? Or just idle only?

Chief · 11-02-2009, 10:46 AM

im getting all of it done sensors/injectors and tables and all rescale....

Yes the connector could be causing some issues with the idle and WOT (if the voltage never makes it to peak voltage). Normally its just idle that gets affected, but we have seen a few datalog that never make it over 3.0 volts just to find out that the customer needed a TPS sensor or the connector repair kit. I would get that done before you get the tune installed, you don't want to be fighting the tune if its just the connector or the sensor.

Im gonna do a data log and post it up, How do you guys get your data logs to appear on the site? I just wanna see if my tps is working right? I stripped all the instantiation off and the wires look fine? Now i just need to log it to see whats going on.

Chief · 11-02-2009, 12:17 PM

My tps sensor is reading 0.0 volts!

Im gussing the sensor is bad, I took the plug off and took wires out, and check them all wires are ok and stripped the insulation off. Im guessing my tps sensor took a crap. So gonna run and get one and see if that helps my issue. If the tps raw1 and 2 are bothing show zero volts at idle and when im on the throttle than im pretty sure the sensor is bad?

Chief · 11-02-2009, 12:24 PM

Closest one is 45 mins away... autozone wants 55

dollars doge dealer wants 110

NO! you just logged the WRONG pid. RAW TPS always shows 0v

The CORRECT PID is
Throttle sensor Input>
>>>THR POSN

Just log these PIDS and post the link to the Log. I can tell you if your TPS is bad. What Parameters to Datalog

Here's an example of what a crap TPS might look like at WOT:

No that works... Well i did get a new sensor and reset the ecu. It seems to be BETTER but it still sticks? and sometimes after a half throttle second gear and as SOON as i push the clutch in it revs to like 5k? Even though i only went to 3k? and than sometime it will stick one i push the clutch in around 1500rpm ? i dont understand. The ONLY thing thats different is the wot box? You solder in a wire to one of the tps wires. Has there been issues with this?
