Hi, I purchased a set of low-Z 63lb injectors from Stinger 3-4 years ago. They are not the Stinger FID injectors. I'm troubleshooting some fueling issues and want to confirm the specs on these injectors to make sure I have the basics correct in the tune. Unfortunately I have misplaced the documentation and apparently Stinger doesn't offer these injectors anymore. Can you please tell me what the dead-time should be set at in TS? I am using a PiMP ECU, 2.3l, fuel pressure is 43 psig.
Thanks -
VS

Use the low z info from the startup guide or PiMP FAQ, I think it's 1.1ms.

Thx, Ok- 1.100 ms Thx. FYI- I was getting conflicting info from TS and the PiMP Startup Guide v1.4; TS v3.0.60.61 for MS2 3.4.2 seems to indicate ~0.7 ms for low-Z; " Injector dead time.
Typically 0.7ms for low-z (~2.5ohm) and 0.9ms for high-z (~14ohm) or low-z injectors with resistors. " While the PiMP start-up guide v1.4 seems to indicate 1.1 - 1.2 ms for low-Z and 0.7 for hi-Z; " For factory 2.3T injectors, or Bosch & Delphi Low Imp, use 1.1. For TFX Low Imp, use 1.2. For
the High Imp Siemens Deka 4 Motron injectors we sell, use 0.7 " If you could help me understand the apparent discrepancy I'd be grateful. Thanks for the clarification. -VS Attachment DeletedAttachment Deleted

TS info is for generic megasquirt with peak and hold injector drivers, you don't have that, you have a PiMP. So use PiMP specific info.

Hi I'm in a similar situation I purchased the FID 81lb/hr injectors and lost the info. Need the dead time. I have the pimp XS and the full sequential coil near plug set up. Thank you in advance for your help.

All FID injector data is in the PiMPxs FAQ thread.
