no spark

what specs are the f series injectors?

[vlad01]

ones I got are stock length, 6 hole, USCAR connector and around 40 Ib at 3.5 bar, about 36 at 3 bar iirc.

The1 sells them and with full flow and offset data so you can ensure accurate tuning.



Before you take the plunge, I would retest your ignition with all the injectors unplugged and see if your spark comes back to spec. You want to know for sure that's the issue.

Yeah it did and at work we just got a few sets all flowed and checked at the same time so my boss gave me a set from one of his car cause he's upgrading so I at least know there 100% genuine they worl and have just all been matched

[Kevspec]

Ok I've put new injectors in New set of bpr7efs plugs new oil and changed scaling as per kinjflow spreadsheet and thibg still runs shit house and all over the place. I should also note on start up for 5 seconds engine light is on but doesn't show codes and once light goes off that's When it really starts to run crap

Post up a new log file of how it is now

[Kevspec]

I'll try log it but it likes to drop connection when I try and start it which is making it more fun to figure out what the issue is

[Kevspec]

here is the fault i can see the injecgtor bpw staying nsteady then jumps to 60+ clearly thats the issue i think

[Kevspec]

and here is my bin i havent changed anything except all the kinjflow to suit the injectors. was running fine then not. just seen all the bpw is set via coolant temp. if my temp sender is faulty is it posible to send faults to the ecu and spazz the injector output without showing in the logs?

[delcowizzid]

You are still using that broken tune that I suggested you get rid of and start from scratch you have all sorts of settings changed that should ldnt be messed with. But looking at thd log you may have major rf interferance as rpm is all over the show or you are revving it up and the tps isn't working. Tps is mostly steady at 12 % the whole log

[Kevspec]

i copied the fuel and spark data over to a new bin file. it droppped connection a few times and yes i had to rev it a little until it stayed running with tps steady at 12%

im going to swap a new coolant sender tomorrow and see but ive also put factory memcal with factory injectors and still doesnt make a difference
