anyone know the correct flow rate for inputting 80# siemen injectors in the DHP Powrtuner? i saw one on CGP but wanted to see if there's another calculated format i can possibly try out.

Hey Freeman, Isn't there one in the import thingee on DHP?
10-04-2011
umm i dunno lol. i dont even remember the website for DHP anymore lol i'll go and google it

No ...
When your in the IFR table, right click and choose import. Then look around for injector tables or it says what it has sitting there to import.

or...aslk Pat. he should have all the stuff I had. And I think there was an 80lb in there.

ah i remember now, you're right theres a spreadsheet in the dhp folder that should have the various injector sizes. also one other question, if the maf and/or IFR is off would it cause erroneous trans shifting/converter issues? someone on CGP posted under the pcm and tuning about tuning for 60# and said he felt that his trans/converter was acting up.

bill, the dhp folder only goes up to 65# injectors

See...this is why I dislike DHP..lol Ask Pat..he might have it in a bin.

This is as about mathmatically simple as anything gets here guys..Originally Posted by fst
33 (size of stock gtp injector)/80 = .4125
take your stock value (I think its like 213), and multiply it by the size difference.
.4125 * 213 = 87.86

Some maf tricks and such will cause this (if you are running a AFC/modded maf on 42# injectors, you may find issues).someone on CGP posted under the pcm and tuning about tuning for 60# and said he felt that his trans/converter was acting up.
The problem most people have with big injectors is the fact that they are trying to run a factory maf file on it for some reason... but you really need to be using a matt m maf / afc or something that moves your maf curve back within "stock range" and skew your injector table significantly.
I have 105# injectors in my car and my IFR values are around 150.... when they should really be around 60 or something, all because of my AFC pulling out 20%.

DH do u have a sample of what Matt M uses? im using an AFC as well aside from a tuner

It would probably be easier for you to make your own as anything I have is going to be for a fixed afc and a 99 maf... But the scaling is not very easy to do mathmatically, so I can try to send something over if I get my laptop fired up sometime.
