So I recently decided to get a set of the DW 1300cc injectors because of a build I am working on. Since there were no clear scaling and latency’s I got starter set from another member and worked it from there for 93 pump and E85. Now I set up my scaling and latency’s mostly to plug right into any Cobb map and not be very far off. Just monitor your LTFT’s and AFR’s and if any fine tuning is needed it should be very easy.



I will have to say one thing about these injectors they are way quieter than others of the same size I have seen. Check out the video below of when I started tuning them and how quiet they are, really I can’t tell the difference between them and the 800’s I had.
Well other than a bit of a size difference since they are just a hair taller but a non issue and full drop in injector.

So here are the scales and latency’s; (Will update if I perfect more)

E85 Scale = 886
93 octane pump = 1170



Now remember these will only work correctly if your MAF is calibrated correctly. If not you may end up way rich or lean at WOT but be fine at a cruise. If your having issues PM me and we can get you sorted out.

So far I have been really impressed by these and am glad I went this direction. Very smooth at a cruise unlike some others I have used. These just seem to work so effortlessly and fluid. Also side note with these with E85 and a maxed out Green @ 8000rpms I am right at 70% IDC on a Walbro 255 pump and stock FPR (Do have large volume rail). So if you’re planning on running E85 on a Red or Black these are a perfect choice.

Just a little extra food for thought here for some of you also.
I am running a 255lph in tank pump and with my mod's tuned for peak performance I run 65% IDC on 93 pump gas. So by using a typical B.S.F.C. (Brake specific fuel consumption) calculator I can deduce that I am running 505 BHP. To support the 505 I need a 200lph pump running 43.5psi to sustain my my IDC's.

Now running E85 my IDC's are 80-85% and thats right where I am maxing out my 255lph pump. Here are some cool calculators to help you figure out your fuel consumption needs. Remember these are based on gasoline and E85 requires 33% more flow so keep that in mind.

These calculators suggest that 1500's and a Bosch 044 inline might be a good choice for a Red/Black on E85. Is that accurate?

too bad we couldn't figure out my situation with my brother's car going back 1000s it is i guess. I really think there's something faulty about his particular set of injectors he got. I think he's gonig to send them back to DW and have them tested and hopefully warranty them out.

ps. thanks for starting a DW1300 thread right after i start one here haha

Don't feel bad. I went to ID2000's and had to roll back to DW1000's as well. It had warm start issues that I didn't have time to figure out. I hope to revisit that once I get some other problems sorted out. I wish these injectors had been released before I bought the ID's but such is life.

i honestly think he should just go back 1000s and not worry too much about his 95% duty cycle at 7k. he never even races it really. maybe, maybe he takes it out to the track once in a while. but why go through all that hassle. me and him are basically neck to neck with our cars making 450+whp and now that i've focused on buying a house i'm learning to be content with my set up. I think i've gotten rid of the MOD monkey from my back for a while. think being the key word in my last sentence.

So he's just been trying to keep up with you and it's all your fault? I'm not surprised.

Cript... 120% is where the injectors max out in the ECU. So 100% is actually withing the limits that most injector manufactures recommend (80%).

Side question, what does your brother use for fuel pumps with his Red on E-85. I'll have that setup on my car real soon.

Golden...... WHAT?....... are you sure about that?! if so, why the hell does it work that way!? who makes 120% the new 100% can someone comfirm this for sure? if so, why the hell are we worrying about our 1000cc injectors?!?!?! he's running a 255 walbro

Mlomker, yeah haha he's always trying to one up me he went all out with a full race exhaust manifold and ams downpipe, where i have a ported manifold and Greddy downpipe (cuz that was the only one available when i bought mine). but we still make the same power

I have seen numbers greater than 100%. I believe Tephra has said that ~120% is max in a thread on here... somewhere.

TEPHRA, where are you? i need you to confirm this.

Here is a thread that somewhat talks about it. The OP is hitting 115% IDC and is trying to fix it.

ummm.. interesting read. it sounds like my brother ran out of pump when the 1300s where introduced, and it wasn't the injectors after all. i only read the first page of that thread and didn't see tephra saying 120% was the max. i'd love it if he could comment on that in here.

It is VERY well known that the logged IDC in Evoscan is not accurate. You lose control (ie, cannot richen the AFR) over the injector when IDC hits around 115%. So hitting 90-95% is not a big deal. Ther is no problem at all with 90-95% on a daily driven Evo.

I ran out of single Walbro at 420whp on my tuner's dyno whereas the DW1000 injectors are currently fine at 430 on a double pump. I'm not sure what the actual limit is on the 1000's since the 3" MAF on my intake is the current limitation in my setup.
