Did they tune the car?

Pretty safe to say almost everyone that has tuned their own car has experienced this issue. The difference being that we have our laptop in the car and when it happens, it's literally 10 seconds of tuning to sort it. Would you be happy to plug in your laptop and sort this yourself? It is a very simple process and there is no risk of harming your engine (if you are worried about that).

Who tuned it? Have you spoken to them about the hot start issue yet?

Seems like no one wants to answer my questions these days lol.

What ECU are you using? Sounds like an issue with the hot start mapping.

Just checking, does the engine turn over and not start? or is it just a single click and doesn't turn over at all?

I'm hoping it's something as simple as the ECU is looking for an external MAP sensor, but he is trying to use the onboard MAP sensor.

You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc. What have you been doing so far to learn how to tune?

@Haggerty you still haven't answered my question. Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are. This process would be a lot quicker to figure out if we can remove user error from the equation.

@Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?

I don't understand what the issue is with, turn the boost down and start saving $$. As soon as you can afford the supporting mods, turn the boost back up. If the car is running fine, enjoy it. Turning the boost down isn't going to kill you.

Hmm not really, I'd say its race car life or modified car life when you make 3 or 4 times the power Nissan designed the car for lol.

Ah coolant overflow, previous discussions make way more sense now lol.

Is the only issue that the oil catch can is getting filled on hard runs? I'd be thinking more about oil control issues rather then the head lifting, especially as you aren't seeing spiking in the coolant pressure. Do you need restrictors in the head, or better drains from the head? Does the sump need venting to the catch can?

My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

I'm not normally one for posting random videos, but I thought we'd all appreciate the honesty about how broken our cars tend to be lol. Genuine skyline life here.

Sounds like the perfect excuse to buy a quickjack.

He still hasn't said what the fluid was, saying "Tomei fluid" isn't enough detail. Using my crystal ball, sounds like the diff oil was 80W90, that is the only "Tomei fluid" I can find anyway. This problem might have been solved in 5 seconds by using a decent 80w-140 oil.

Are you 100% sure this isn't tune related?

Yeah mate, never miss it.

What are the stickiest tyres you've used so far?

I don't see any issues here. I've been saying all along this is a big job, the price reflects that. When the car comes back perfect I'm sure it will feel like money well spent.

Did you pay with a credit card? I'd be putting a charge back through then finding a new sparky to sort it out.

Was the car running before he touched the car?

What have you tried so far to diagnose the issue? I'd start with checking fuel pressure.
