Ok great, thanks for feedback guys! I have been playing with my tune and think I have it smoothed out as it can be and I am very happy with it. My vacuum settles around 15-16 and that seems to be in line with what you guys have.Do you guys use idle air clamp with speed density?

Why is there a tpsdelta 0 value in BaseTipInTPSAdj? If I lightly touch the throttle there is not enough change in tps to give a tpsdelta 1 value. So does tip in at tpsdelta 0 only give a small squirt of fuel in these very light throttle change conditions? Does it respond with a fuel squirt...

Hey guys, I am trying to improve my idle and I can only get the vacuum to 16.4 in hg at best. I do have 268 (GSC S1) cams and I am wondering what vacuum people with those cams have.When I watch my wideband, it does seem to bounce around mainly lean and the idle is not rough, but it is not...

I found grease on the back fingers of my previous pressure plate. I suspect from the tob, presumably from a misadjusted clutch pedal, master cyclinder and slave cylinder. When I installed my new clutch and tob just recently, I took great care in following the service manual explicitly for...

Ok, so a lot has happened this past month. I replaced my clutch with a South bend and replaced the tob with an oem. I also rebuilt my driveshaft while I was in there. The tob was the cause of the intial issue I believe as the car is running great. It is not dying on me when I press the...

Alright, I adjusted the SAS to 1.25 and warmed up the car and made my calibration changes. I then pushed in the clutch and blipped the throttle and it died.So I adjusted the SAS to just about 2 full turns out. This about maxed my BISS screw turned fully in. I blipped the throttle again...

Yea, I just called there as well and $1600 is way more than I am willing to pay. At that cost I would much rather go with an aftermarket seat that has more comfort than our OEM seat. Also, they will not sell directly to you, for that price you have to go to one of there authorized service...

So I did a quick test last night and here is what I found. I turned the SAS 1.25 turn from my original 15/16th of turn. I readjusted my TPS voltage to 0.63 vdc and started it up and rev’ed the engine with the clutch pedal pressed to the floor. The engine did stumble a small amount after RPM...

Are you saying I have to turn the idle switch in more than 15/16 of a turn to open the throttle blade more with throttle fully closed. I believe that was the value in the service manual... This has been happening for sometime but now seems worse this first time driving this year

Hey Guys, I am having an issue when I press and hold the clutch pedal down and blip the throttle while clutch is still depressed, the engine just dies. It does not sputter or hesitate, just literally goes to 0 RPM.Now, I have found numerous threads discussing this exact issue however, they...

Here is a pic of the housing crack. You will notoce a few cracks down the shoot!

I think what I will do at this point is rebuild the MHI 14b. I will use the turbine housing from the ebay turbo though, assuming it is not cracked, as I have not looked at it yet, but it is brand new and there is no shaft play in the turbo. I do plan on porting the both the exhaust mani, O2...

Hey tuners,I have an MHI 14b that I was going to rebuild and install on my spyder gst. The car is all stock except for an ebay 16g turbo the previous owner installed. Now, the turbine housing on my 14b is cracked of coarse, so I was going to use the turbine housing off the ebay turbo on the...

I missed this when I was responding to my thread. Thanks for info, you seem to have this vey well detailed. I will review your thread today!Thanks

After reading through a few well put together "how to" posts it seems I have an answer to my second question and it appears to be stapled to that bow. I can clearly see it stapled in post #2 in the link below. https://www.dsmtuners.com/threads/convertible-top-replacement.528063/I could not...
