STI Dead!
Hi , Im realy stuck here, I installed Perrin 800cc Injectors and high flow fuel rail kit , Im running a Hydra and the car was running fine with the original 550cc injectors, except for the fact they where at 100% duty at 5000rpm. So I decided to go ahead and change the Injectors,
As far as i know the only thing I had to do once the new Injectors and rails where installed was to go into the Nemisis Injector change trim option and enter in the old and new injector sizes. then the program would make the neccesary adjustments. But now the Engine Cranks but nothing happens . What do you think?? Ive even tried entering 760cc instead of 800cc injectors but still it wont start.

I would guess you don't have enough fuel. The automatic calculation is not perfect. Generally I put in much lower calculation just to pull some fuel out. Regardless Phil should have a map if you bought the Hydra from him. If not, the car should start with the 550cc map and then you will have to retune.

Injector trimming will pull out too much fuel with 550 and 800cc values.
Try changing the values by -***37;10. |

The car *should* at least start using the stock fuel injector map and the perrin modified injectors. My car did start, but idled at about 9:1 AFR.
Are you sure you have fuel pressure, are you sure the injectors are firing? Maybe it is something silly like you got the return and supply hoses backwards. |

Im coming to the conclusion that my problem lies with the cranking enrichment map.I know how to access the Cranking Enrichment map but Im trying to figure out how to change the values so I can atleast get it started and drive it up to the tuner ,but cant figure out how to actually make the changes,..Anyone have experience with changing the values in the Cranking Enrichment map , on a Hydra??

when your on the cranking enrichment map, youŽll see where it turns yellow and that will be your temp. give it more enrichment % untill it cranks.... when your temp comes up youŽll notice it goes into another range, I shut it off and and tried to crank it again to see if it needed more % wich it did. I kept doing this untill my engine was fully warmed up. after all that was done I went to the post start enrichment and gave it a few more % to keep the engine without turning off. and finally I adjusted my fuel map at idle. |

Most of these changes are volatile changes, meaning if you want them to stick, you would need to download the map from th e ECU, then re-upload it back to the hydra in order to make them permanent. However, you only should do this after you get the car running. During the trial and error process, you can leave the ignition 'On', and change the values (press enter to save them), then try starting the car, and repeat. If you flood the car with too much fuel, you can hold the gas pedal WOT, and the hydra will crank the car over + fire the spark plugs without turning the injectors on to help clear it out. |

If this is an Element Hydra then just email us with your serial number and your modification list and we will email you a new base map for your modified stock injectors.
If the car cranks and makes no attempt to start you may have accidentally altered your crank triggers or downloaded the template map. Thanks, Phil www.elementtuning.com |

Ok Tuner cant get the car going with the Perrin modded stock Injectors, so Im stuck now.
Either I send him a map to get my STI going or Il have to have the stock injectors installed again. Phil I sent you an email for a map to get my STI going, I didnt purchase the Hydra directly from you, although i really wish i did, If you can please help me out with a map Id really apretiate it , if there are costs involved for you support please just let me know , thank you. |

Whenever you need a new map please email us instead of trying to have your tuner do it. We have base maps for all the popular modifications. It doesn't matter that you did not purchase your Hydra EMS from Element Tuning. All that matters is that it is an Element Tuning Hydra, which you have based on the serial number you sent me. Thanks, Phil www.elementtuning.com |

Update on my STI , that is finaly running after being at the Tuner for 3 weeks. Problem was the Perrin stock moded Injectors. I had to replace them again , put back the stock original Injectors and the engine started fine.
