DOUG @ ECS

Drew thanks for the heads up on this. Ace, I am terribly sorry the issues you are having here and my delay in response. I have been away from the forum and our office for at least a week. I asked my guys to handle this for me but I see if you want a job done right... I can't apologies enough.

OK, so our stg 1 fuel system does not come with a regulator since it utilizes the stock regulator normally. Where the problem lies is the fuel system on the ZR1 in this case. Our stg 2 kit comes with the factory regulator block off and a boost referenced regulator with a return line. Stg 3 uses an Aeromotive pump, and stg 4 is usually custom for the build.

I will personally sit down Monday and put everything together in an email for you with tuning instructions etc.

Also if I need to send you additional parts after reviewing what is needed, I will send them at my expense due to how this was poorly handled on our part.

If you could, please send me a PM with your email.

Thank you for your patients!

Mine as well make that double I bought your fuel pump stage 1 for my zr1 as well. Looking forward to getting it installed.

Any updates?

I pm'd doug couple days after this thread, he got back to me within a day or two saying he's getting everything together that we will need.

We have to bypass our pump control module and add a regulator and return line and have a fixed pressure in the system

ZBADESTZ@Straightline

Ace did you do this yet?

Is it the cure for the kit? Do they have a kit with all the stuff?

Does Fore have 1?

I installed the stage 1 kit on my car with the Bosch pump. It worked great. 1 guy has an issue installing it and everyone's bashing ECS. Typical forum behavior

ace32x

didn't have an issue, wasn't sold the correct stuff or supplied with the correct information when purchased. Doug has sense remedied the situation. The stage one kit alone isn't all you need. You need a return and regulator and need to bypass the control module for the oem fuel pump.

frc

Yeah Ok. All I had was the basic Stage 1 kit. No return, no regulator and didn't bybass anything. Carry on.

ace32x

Fuel pressure spikes when the pump hits and causes the stock pump to reduce pressure and throw codes/stumble, maybe since your running the smaller pump it's working alright?

Ballbearingturbo

You both used a different pump.

ace32x

used the pump Chris at ecs suggested. Originally was going to use the 044 but he said the a1000 was the better pump for what we were doing.

ZBADESTZ@Straightline

Maybe the 044 doesn't make as big of instant pressure spike as A1000...

Are they both ok with E85?

ace32x

was told the 044 wasn't that's why we went to the a1000
