need more info ie. what are you talking about. do you have any mods? did it just do this suddenly? are there any codes? need more info also check for boost leaks!!!

I'd say try gas first. 3 year old gas may run an engine, but it will most certainly not provide power with boost. I would drain the gas out of the tank and refill with new. I can't believe that you would post about this before trying fresh gas.

I installed a Neo upgraded with the latest software on my 88 7mgte supra preparing for future upgrades. Air maps at 0 all the way. When I accelerate past 5000rpm, it has no response to throttle until the rpms fall below at least 2k. Throttle still registers on the neo. Neo still registers...

I just installed one in my supra yesterday. Had no problems with it. Fired right up. You say yours is an 89. Is it the early ecu plug or the later. the way to tell is the early has a connector config of 10,18,24 pins per plug. The later is 22,16,26. Something I ran across with mine (an...

The safcs are not at all as sophisticated as the maft pro. They are not set up for receiving inputs for a/f. Wish I had a maft pro.:cry:

I really doubt that they were upgraded to 550s. It is very difficult to use much more fuel in the same motor without forced induction. Now if he put a turbo or supercharger on it then maybe he would need injectors that big.

Total airflow into the 1uz is greater so they made the afm bigger. 1uz afm allows about 25% more unmetered air through than stock 7m. So with this swap, you can get 550cc injectors(from something else) which are 25% greater flow than stock injectors so the fuel maps on the stock ecu are...

not sure about the exact rating, but I know that they are not 550s. If you think about it, each cylinder in a 4.0L V8 is only .5 liters. Each cylinder in a I6 3.0L is .5 liters. Seeing that the V8 is not turbo and there is one injector per cyl. also the air flow per cylinder would be...

the neo tunes decel air in airflow percent just as the previous units. I asked the guy at apexi if they were trying to fix the problem with decel air, he said not to hold your breath. He even suggested to get the safc2 unit instead. I guess they don't hold it to be very important. I sure...

Taken from p23 of 'my' neo user manual: "If the throttle is rapidly released on a vehicle with a hot wire and Karman turbo air- flow signals, the engine may be stalled by blow-back. " Then.. "If the throttle opening goes less than the value set by“Dec Air”at a rotation speed lower...

grim., I think you need to read through that again. The karman is included.:icon_bigg Back to the problem. First of all, I would suggest that you swap to the 550 injectors so that you get the fuel that your engine needs. I bet your neo is adjusted WAY up (20-25%) to compensate for the lack...

I don't have any electronic control on my supra yet. I am trying to figure out how far I want to go with this one. For my power goals(400hp maybe 500 max) I am sure that a safc 2 or neo would be fine, but I would really like the spark control and speed density that the maft pro is capable of...

I have messed with it a little on my friend's turbo 280z. But I couldn't give you any comparison notes because I have not messed with any other standalones. For a while I wanted to use it on my 7m engine swap in a pickup, but then I decided that for my power goals it would be much easier and...

I have a custom exhaust made from 2.5" aluminized steel. I just did a rebuild with a t04e turbo, so I just changed the exhaust while I was at it. What I took off was a crappy 'do it so that it works' job. That is what was on there when I got it. At the smallest point, it was less than 2...

I just ordered the fork from the dealer along with a couple of bearings and fornt seal. Total was 163. I don't think that is too bad. He will have them for me by the end of the week. Time is important to me b/c it is torn down on my friends bench. Also I just did a 5 speed swap last...

I figure that was it, I just wanted to be for sure. Still open if anyone else has found a supplier.

I have torn down my trans because 1st gear started popping out of gear. It is not quite completely apart, but I did find that the no.1 shift fork has a piece broken off on the hub surface but it did not damage the hub. Anyways, I would be more comfortable with replaceing it. Does anyone...

If it is similar to the 22r truck, use mkii motor mount brackets and the thing bolts right up using stock motor mounts. good luck with that.

Have you had any problems with the alarm system? I had a problem where the car would not crank by the key, but I could jump the starter solenoid and it would start right up. It was the starter kill circuit on the alarm. If you have the origional owner's manual, it tells you how to disable the...

I rebuilt my 7m and about 2000mi into it, the coolant system was running at unusually high pressures. I kept trying things left and right while denying that it was the head gasket. But it didn't quit until I replaced the HG. Not saying that's it, but don't shut out the possibility.
