Has anybody used 750cc Rc injectors with a E-manage ultimate?

 

I believe that Emanage cant flow or control injectors that big it doesnt have complete control over the injectors like the UTEC of a Standalone.

 

I have tuned alot of cars with the 650's. Iam right now in Orlando FL. trying to tune it but Iam having a lot of problems with this one, and Iam wondering if the injector are to big. The car run perfect (598hp @19psi) but wont idle!

 

Sharif has mentioned in several threads that you need to flash the ECU for 550's and then finish scaling them with the EM . I think TS can flash for 750's though

 

I ran RC 750's with the EU. You have to flash the ECU to 650's so you can scale the 750's.

 

On another note, where are you in Orlando. I'd love to meet you and see some of the tuning. You at Titan or Aerocomp?

 

Its hit-or-miss with 750cc injectors and the EU. Usually the idle is pretty rough, and we have to run really low fuel pressure to get the cars to idle cleanly.

How much fuel pressure are you running?

 

Iam running 35psi with the vacum on Sharif.

 

Iam @ Central Florida Turbo.

 

Cancel the injector scaling in the parameters section...turn it off.

Instead, goto the airflow adjustment map, and put -50% the entire map.

At this point, try free revving your engine to about 2200rpm or so. What is your AF ratio under this scenario? If it is near 14:1, then your solution is an idle increase, via TS or AAM.

 

have you tried dumping a lot of extra fuel in during idle. it has helped my idle a few times...


im in orlando too. CFT has some fast hondas!!!!
