Ok, So just about a month ago I took my car, a 89 T2 w/ a E8 to RRR dyno tuning in Santa Ana, Ca. Nelson tuned my car, AWESOME DUDE! Took all day cause of my injector issues... but Car PULLS HARD! made 360 at the wheels, Im VERY HAPPY!! We tuned on 100 octane, and its a track only car so thats the type of tune he performed. ok Ill get to my point... Its currently registered for the street so Ive driven it arouind a lil bit, it seems to have a hicup/hesitation under light acceleration & very light throttle at about 0/1psi and alomst always at 2500/2600 rpm. I can see the wideband from its steady position drop all the way lean for a split sec. Its was about 105 degrees that day. I live 6 hours away from the tuner in the SF area and its about 75 on avg. Where should i start to correct this problem??? Im not afraid to play with the haltech software. Is this a stagging issue? or should I just add fuel in my fuel map at that rpm & range? thanks in advance for any help

 

give more info on your injector and ecu combo. i had this resault on my e6x with 550cc and 1600cc injectors.

to say the least, the 550cc is like a water gun compared to a 1600 is a garden hose. not much accuracy.

 

staging issue,, on e8 there is a staging correction map that can be used to alter this momentary point

 

It's an e8 with 720 primes and 1200 sec. Ok, I think I know where this is in the program. I'll have to open it up and play with it a bit. Any suggestions on how I should make the adjustment ?

 

I could use some suggestions. There are 2 correction maps for stagging. What should I do with either one?

 

really...... 193 views & not one person can give me advice or suggestions?

 

The only information you've given is to basically say, "my car doesn't run right". Not sure what you expect. Have you read the manual?

Get some good datalogs showing primary injection pulse width (not duty cycle), secondary injection pulse width, MAP, TPS, RPM, and AFR. Post those and your map. It would be best if you could sweep across the problem area as slowly as possible with steady throttle application. With a little information, you may get some help.
