My car seems to get floded every time i start it up, even if its hot,the only thing that seems to help is to start it with my foot on the throttle which i know is not good, it runs fine once its started though, does any one out there have had or knows what is the problem thats causing that?

emanage blue retains all factory cold start programs, should not affect cold start or hot start. Just changes fuel mixtures and timing under normal running conditions. I would say its more likely to be something else like injector, or even more likely fuel pump ecu/relay - common problem apparently? never experienced it myself?

i tried many different brands of injector cleaners and that did not make any difference, i manage to find someone selling a set of soarer injectors bought them and installed then, and that did not fix my problem i also noticed after installing these new injectors i got a error in the dash {engine electrical} so i ran the diagnostic and got code 52, i find this strange cause when i got this code before the car would not rev past 2500 but now it boost fine just has this error, i am now wondering if this problem is in my ecu? what do u guys think? what els can i try? it seem to be fine on a cold start, first start in the morning is fine it seems too rich but it starts ok but once it warms up a bit it flood every time.i also find that if the car is like going up a hill or something and i tap the throttle a few times it will load up and stalls.

Have you tried the fuel pump mate? I've got the exact same problem.
I get error codes 13 (cam angle sensor) and sometimes error code 52.
Now my theory, is that the fuel pump is beginning to fail. Because it is not supplying enough fuel, the engine will knock (bringing up error code 52). Because it is knocking, the engine will retard timing sending a signal that the cam angle is off (error code 13)??
Anyone think I am on the right track? I've been chasing this thing for about 6 months, it comes and goes.
Garth, when you bang the fuel tank after it doesn't start, will it start then?

i have never bang the tank cause i never suspected the pump,i dont believe my problem is the pump though because when it dont start i just turn the pump off cause i got it on a switch now i got tired of pulling the efi fuse so i just switch the pump off and crank it with the switch in the off position the engine will now start after a few sec thus proving that there was exes fuel in the engine so when it fires up i just switch the pump back on and i am good to go.

So, you are bypassing the Fuel Pump ECU with a direct relay to from battery to pump... ?
Have you changed fuel pump ECU's then? Run the Fuel ECU bypass by bridging FP and B+ in the Diagnostics port in the engine bay (right of the plenum),and if she runs fine after that, then you need to change your fuel ECU. This should only be done as a temporary measure as it can fry your main ECU apparently.
If that fails, I'd be taking it to a mechanic to check if there is fuel pressure in the lines using a gauge. If there is pressure, I'd be checking the injectors.

yes, my switch setup is totally independent of the fuel pump ecu, my guess is that the fp ecu failed while the previous owner had it and he did the bypass in the diag port, my electrician got rid of the bridge in the diag port and put the fp on a relay and a switch, i know there is fuel pressure cause the engine gets flooded without fuel pressure that would not be possible, my concern is why are my injectors letting so much fuel down in the cylinders causing it to flood, the error i am getting is only after i installed a set of used injectors which i will change back to my originals as soon as i get a chance,is it that my ecu is bad and the duty cycle on my injectors is letting them stay open longer while cranking? is this something a week battery would cause ? because its made in 2008 ?2 years old?

Garth, suggest you get your old injectors cleaned and calibrated for flow and put them back in. Just sounds like your replacement injectors are too big for your application. Particularly if they haven't been tuned to the Emanage Would have thought your O2 senor should have leaned them back though, unless it's not connected to the ECU. Perhaps you tuning man should be able to sort it. cheers David

it was said in a previous post that the emanage blue retains the cold start programs so it should not make any difference and my car was been flooded on starts not while driving,

Leaking injector . After you start the car and drive it its fine . Once you stop it, 1 or maybe more of the injectors are sticking open slightly . Letting fuel into the cylinder . My mate had same problems on a GTR . Try swapping back to stock injectors ?

E-manage won't affect cold start UNLESS duty cycle on injectors is too high at low RPM...if duty cycle on injectors 100% on low rpm it will flood at low rpm. Post up a screen shot of your fuel and ignition maps on your e-manage. It is very unlikely that a good tuner will have duty cycle on injectors at start up rpm modified at all...thats why e-manage should not affect start up programs, the factory settings are retained.

Actually come to think of it it makes no s**t of a difference because it was running ok after the tune. It will not be the E-manage unless the settings have somehow become corrupt, post up those maps if you can.

sorry man i dont have the maps and i do not know if the tuner still has them , i am in jamaica and the tuner is all the way in kingston, 3 hours drive away but i will contact him by phone and see what i can get out of him, but if that was the problem couldnt i just take a screw driver and make some adjustments to the emanage? it has 5 twister screws?

also what colour should the lights on the emanage be mine looks green and flashing, i don't know what kind of thing could mess up the program in the emanage the only thing i can remember is when the guys changed the injectors the car was not idling right cause the coil wires going to #1 cylinder came off and was touching making sparks but they put them back on and it ran fine so i don't know if that could mess up things.
