like the title says....if you are please chime in, i just installed my 37r and dont have money for an ems yet, so i was wondering if i could just get my ecu flashed for 1000cc injectors....but al recommended me to go smaller, but when i ordered from BR they recommended me to go even bigger than 1000ccs, so i feel if i go smaller i wont have enough fuel, so for those of you who dont have ems, please let me know what setup your running and what management. thank you! also let me know what tuner you use

 

YES! You can reflash the ECU for 1000cc injectors and they will work fine..

Anyone with experience with the AEM EMS tends to recommend larger injectors, and anyone with experience with the stock ECU recommends smaller, I can tell you from personal experience that the 1000cc injectors on my GT35r car are indeed a little larger than necessary with the stock ECU.. But they do work fine.

 

I think you will find the limitations of your MAF before you ever find the limitations of the stock ECU.. They don't go hand in hand, so if you do your research you can find solutions that work really well as you need to make changes.

 

I also have 1000cc injectors on the stock ECU. It took me a little while to get the scaling correct and the trims in order but the car idles like stock now.

 

just save up and get the EMS well worth it.

 

yeah im planning on it, but have to have something till than!

 

what are you tuning with?

 

Its not worth anything if you can't get the car inspected.. I don't know if many of you have realized this, but the inspections in many states are now electronically tied into the registration/renewal process, and they are able to tell fraudulent inspections.

I have to appologize, this wasn't really directed at you specifically.. Just getting tired of the "EMS Solves everything" opinion on engine management..

the EMS is fantastic for a car that doesnt need to worry about inspections and OBD-II, however 90% of us **DO** have to worry about this, whether everyone realizes this or not, at some point in the near future the cars will have to pass with the OEM ECU in place.. There are very few states left that don't enforce this, and that changes every year.

Nuff said.. With the level of technology out there, by the time you make your decision on which direction you want to go, you'll have a few options to consider depending on what you want to do with your car.

 

ah thanks for that! i totally forgot about emissions, every two years, mine due again in about a yr, since its a 96+ nomore sniffer, they only do the obd II plug in, which certainly wont pass w/ a standalone......

im so confusedddddd

 

I was running 1000cc injectors on my IX with ECUflash and it wasn't to bad at all!

 

It sounds to me like you have the cart well before the horse.

What fuel system are you using?

What supporting hardware (e.g. exhaust, cams, IC, etc.) do you have with this setup?

What fuel?

Are you doing this with a stock engine?

Do you not plan to dyno tune this car???


When someone mentions "37R" and "I don't have money" in the same sentence, a dozen red flags pop up. I get the impression that injector size may be among the least of your concerns.

 

BR 37r, RNR 3" TBE, BR Race FMIC, BR Hard IC piping, HKS 280 cams, BR modified high flow fuel pump, precision 1000CC injectors, smc alky injection,arp head studs, exedy twin carbon disc clutch,

Im on the stock block right now, working things out w/ BR for a motor build over the winter.

I wanted to get it dyno tuned, hence why i called al, but he recommended something smaller for injectors, thats why i made this post because i knew there were ppl out there using 1000ccs in the stock ecu

 

If you intend on using 93 oct + methanol (M15 nozzle I hope), the 1000cc injectors are plenty big - assuming you get proper tuning. And where proper tuning is concerned, forget trying to get any power out of it until you can get a dyno tuning session. In fact, a mail-order reflash should not be considered for anything except getting from points 'A' to 'B' (WITHOUT methanol) until you can have it properly tuned.

 

And this is the reason i have florida plates dont have to worry about state tests.

And staying on topic yes you can run 1000cc its when you step up to 1600cc with lets say a 42r on stock ecu is where the problem comes in then thats when you have to setup to a ecu. But anything less then a 37R you can run stock ecu's ams has done a few cars with the same setup or i think it was a 35R im not a 100% sure.
