Hi guys

after cleaning the throttle Body of my SR3 the engine dosn't fire up. Spark is ok and I have fuel.
After I went trough SR3 Trouble Shooting I noticed that I missed to set up the TPS.

I dont have he USB connentor so I tried to st up the TPS with the Volt meter. But I don't know which is the correct value for the cosed throttle.

I found 4 different values. 0,2 V and 0,35- 0,37 V which I already tried. Also I read that 2 V is correct but I can't setit up to 2??? Ad Radical Service manuel is a value of 4.0 termend. But I don't know if this are Volt or apple?

Could anybody help?

Cheers

If I don't get the car running this Weekend I will contact RPE

I run a MBE ECU with 1300 engine. But it Looks like I have a modified ECU from ANDY BRUCE. Does anybody knows him?

Thanks for your Support guys. Sound like a tricky Job to set the TPS without the correct Tools frown

Unfortunately I don't get the engine started today. I set TPS to 0.2 V at idle and tried it 3 or 4 time. Nothing. After a brake I tried it again buy moving the TPS slowly during engine cranking. Again nothing (but I'm not sure if this was the best way?)

I can confirm that the TPS is installed in the correct way. Voltage increase when throttle is opening. When the Butterflies are complety open the Voltage is about 4.2 V and I can adjust the TPS voltage from 0.07 to 1.72 at idle.

I will simplify this Job and buy a ecu Interface to read out the correct TPS value. Is the AD0109 - Download Lead from Radical the correct part to use Easimap 6?
I will also buy a tool to adjust the airmass, does anyone has a recommendation?

I already tried 0,37 V but it don't work. Also 0,2 V is not working so I'm a little bit clueless?!?

Before I noticed that I have to adjust the TPS I have set the TPS to about 0,75 V by accident. At this TPS setting the engine tried to fire up and also starts for less then 1 second. At 0,37 and 0,2 it sounds like the engine has no spark or fuel. Of course it tested both and the fuel and spark are fine.

So I hope I will get the correct voltage with the ECU interface. Otherwise this will get really tricky

Actually I can't believe that the enigne doesn't start because of the wrong the TPS Setting. I just tried a few voltage from 0.1 up to 0.7

I did a short Video Clips when trying to start the engine. I bought the Radical just a few weeks ago so I'm not so familiare with the SR3 yet. Before I removed the thottle Body to clean it the Raical straight fired up but doesn't run s well. I guess this was because of bad Setting of the butterflies, but just a guess. Maybe someone can notice a strange think at the Video Clip which helps me to identify the fault

just a short checklist

-spark is ok (just double checked this)
-20 Liter of new fuel (I pumped out all the old fuel before)
-battery is ok and fully loaded
-plug leads were removed but they are in the correct Position (they were marked)
-I smell and see the fuel in the plug holes (also tested each fuel injector)
-fuel pump is working (but I on't know the fuel prssur, but I would say it's ok)

I now opend the Butterfly till you can see a gap and set the TPS to 0,3 V and tried to start the engine. And it start to fire up a second. So I'm a Little bit happy now that it is just a adjustment Problem. I will try some more adjustment to get it started. Maybe I get it running

What would you recommend.
-same TPS Setting (0,3 V for example) and just try to adjust the Butterfly?
-or playing around with both
-or wait till I get the ECU Interface to read out the correct TPS Setting (hopefully ;-) )


by the way is this start up way correct?
1. main power Switch on
2. ignition on
3. crank engine with ignition on

I don't know the tps value yet and just ordered the ecu interface. So it will take a few days till I know the correct tps value

ah sorry with I/F cable you mean the interface?
My problem is that I don't know the correct TPS setting and I hope I can get the correct TPS voltage by reading out the map. I don't think I have the standard Radical map anymore because I have a sticker on the ECU "Andy Bruce tuned 1300"

Or did I understand something wrong and it's not possible to find the correct TPS setting from the map?

engine is running biggrin

even if I had a good spark it Looks like the spark plug was wrong. Spark plug type CR9E1A was installed and I just found a different type of spark plug in my spare part package from pre owner. So I now installed the spark plug type CR9EB and the engine fired up and runs fine ...yeees

Thanks for all your Support and help. Just have to set up the correct TPS and airflow and then the car is ready for my fist trackday in the SR3
