What is the redline to a stock jdm itr motor??? ok so here it is. i have a 98' jdm itr swap with only exuast,stock headers,intake, and stock ecu. ive tried to redline it but when it gets close to around 7900k my motor sounds like its kind of over revving already especially in 1st. but sumtimes it'll hit 8200k just fine in 2nd, 3rd, etc...the sound that it makes when that happens i can't really describe...my only best descripition is that of a over revving soud or its getting close to that point at times really doesn't sound like it should be doing that. what do you guys think the problem is? should i get this checked out soon at a shop???? help is need! thanks in advance!

already searched. found nada.

 

found a site that sells b18c-R saying they redline at 8900 . i don't think so tho

 

if its the JDM then it should redline at 8900 but i change my ecu so it rev to 10000rpm trust me reving this high u don't get power out of the engine

 

The redline is the same as the USDM ITR, unless I am mistaken...

8400 RPM, I think.

I know for sure the rev-limit is at 8600 RPM. I used to run a JDM ITR ecu in mt B16-swapped coupe.

Correct out of a stock b18 but throw some aggressive cams and shift the powerband upward.

 

FAQ's thread is your friend.

 

My stock 98 JDM ITR motor redlined at 8900rpms

 

8500 redline and 8900 rev limit

 

does ne one know why it might be making that noise around 7900k?????????? any possilbe problems why it might do this to my engine???

Then either I don't think you know how to search, or I don't believe you. This topic was covered a week ago.

(a Snap On one though.) none of the kragen ones. or even a VAFC will tell you. since everything is digital, and not analog like your shitty factory tachometer is.

 

Both USDM and JDM ITR's have the same fuel cut.

The problem lies with the factory tachometer. Indicated on the tach is approx 8900rpm's, but as you now know, the factory tach is nothing near accurate.

...Funny, I had a V-AFC2 on my B16 and it verified 8600 RPM as the fuel cut.

 

hook up another ecu and try it then, ur ecu could be fucked, mine was and i replaced it with a chipped p28 and rev to 9k plus all day long

 

fuel cut off at around 8399k sounds right. thats close to what it showed on my 99-00 si guage cluster. thanks for all the help guys!!! by the way, i want to get rid of my stock p73 ecu and i was wondering who chips really good P28, etc... ECU'S??? got any suggestions on people on h-t members or non h-t members????

lol i want to rev up to 9k plus!

 

97 jdm itr with stock ecu using a apexi RSM to monitor the rev output pulse from ecu



proof!!!!!

 

so then which is the actual redline???? everyone seems to have different inputs.

...That also states your speed was 145mph.

All I know is, when I ran my JDM P73, it wouldn't let me rev past 8600 RPM, which LOOKED LIKE 9000 RPM on my CTR cluster's tach.

...Told you guys.

8600 RPM is fuel cut. 8400 RPM is 'redline.'
